Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

.IR errno ,
which is set by system calls and some library functions in the event
of an error to indicate what went wrong.
2008-07-08 12:32:50 +00:00
Its value is significant only when the return value of
the call indicated an error
(i.e., \-1 from most system calls;
\-1 or NULL from most library functions);
a function that succeeds

Valid error numbers are all nonzero; \fIerrno\fP is never set to zero
2008-07-08 12:32:50 +00:00
by any system call or library function.
For some system calls and library functions (e.g.,
.BR getpriority (2)),
\-1 is a valid return on success.
In such cases, a successful return can be distinguished from an error
return by setting
2007-06-22 06:05:43 +00:00
.I errno
2008-07-08 12:32:50 +00:00
to zero before the call, and then,
if the call returns a status that indicates that an error
may have occurred, checking to see if

2007-07-18 20:24:30 +00:00
\fIerrno\fP is defined by the ISO C standard to be a modifiable lvalue
of type \fIint\fP, and must not be explicitly declared; \fIerrno\fP
2007-05-12 13:26:09 +00:00
may be a macro.
2007-07-18 20:24:30 +00:00
\fIerrno\fP is thread-local; setting it in one thread
2004-11-03 13:51:07 +00:00
does not affect its value in any other thread.
All the error names specified by POSIX.1
must have distinct values, with the exception of
.B EAGAIN
and
.BR EWOULDBLOCK ,
which may be the same.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Below is a list of the symbolic error names that are defined on Linux.
Some of these are marked
.IR POSIX.1 ,
indicating that the name is defined by POSIX.1-2001, or
.IR C99 ,
indicating that the name is defined by C99.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while.

This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux.

Add Linux-specific errors, and mark individual errors as being present in POSIX or C99 Hello Kurt, Thanks for your message. > man3/errno.3 was missing some errors. Indeed. > This patch updates errno.3 based > on /usr/include/linux/errno.h as of 2.6.16-rc2. I do not quite understand that last: /usr/include/linux/errno.h is a userland file -- it probably won't tie up too well to a specific kernel version (or am I missing something?). > I also synced the error > description in the man page with the error descriptions from the header > file. This generates some useful info, but also some things that are incorrect. For example, since you are talking about a glibc header, does a particular error even occur on Linux. (See some examples below.) I think you also overlooked the fact that the page says that the listed errors are defined by POSIX.1-2001. So it is not sufficient to just add new errors to the list. On the other hand, it is irritating that the current page does not list Linux-specific errors. And you patch has finally pushed me to do something I've been thinking of for a while. So I've changed the page to mark the errors that are POSIX, and added the Linux-specifc errors, integrating some of your patch. > The patch was diffed against manpages-2.22.

.SH NOTES
2004-11-03 13:51:07 +00:00
A common mistake is to do
.in +4n
2004-11-03 13:51:07 +00:00
.nf
2005-07-06 12:57:38 +00:00
if (somecall() == \-1) {
printf("somecall() failed\en");
2004-11-03 13:51:07 +00:00
if (errno == ...) { ... }
}
.fi
.in
2004-11-03 13:51:07 +00:00
where
.I errno
no longer needs to have the value it had upon return from
.IR somecall ()
(i.e., it may have been changed by the
.BR printf (3)).
2004-11-03 13:51:07 +00:00
If the value of
.I errno
should be preserved across a library call, it must be saved:
.in +4n
2004-11-03 13:51:07 +00:00
.nf
2005-07-06 12:57:38 +00:00
if (somecall() == \-1) {
2004-11-03 13:51:07 +00:00
int errsv = errno;
printf("somecall() failed\en");
2004-11-03 13:51:07 +00:00
if (errsv == ...) { ... }
}
.fi
.in
.PP
It was common in traditional C to declare
.I errno
manually
(i.e.,
.IR "extern int errno" )
instead of including
.IR <errno.h> .
