.SH DESCRIPTION
|
|
.LP
|
|
The \fIfchdir\fP() function shall be equivalent to \fIchdir\fP() except
|
|
that the
|
|
directory that is to be the new current working directory is specified
|
|
by the file descriptor \fIfildes\fP.
|
|
.LP
|
|
A conforming application can obtain a file descriptor for a file of
|
|
type directory using \fIopen\fP(), provided that the file status flags
|
|
and access modes do not contain O_WRONLY or
|
|
O_RDWR.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
Upon successful completion, \fIfchdir\fP() shall return 0. Otherwise,
|
|
it shall return -1 and set \fIerrno\fP to indicate the
|
|
error. On failure the current working directory shall remain unchanged.
|
|
.SH ERRORS
|
|
.LP
|
|
The \fIfchdir\fP() function shall fail if:
|
|
.TP 7
|
|
.B EACCES
|
|
Search permission is denied for the directory referenced by \fIfildes\fP.
|
|
.TP 7
|
|
.B EBADF
|
|
The \fIfildes\fP argument is not an open file descriptor.
|
|
.TP 7
|
|
.B ENOTDIR
|
|
The open file descriptor \fIfildes\fP does not refer to a directory.
|
|
.sp
|
|
.LP
|
|
The \fIfchdir\fP() may fail if:
|
|
.TP 7
|
|
.B EINTR
|
|
A signal was caught during the execution of \fIfchdir\fP().
|
|
.TP 7
|
|
.B EIO
|
|
An I/O error occurred while reading from or writing to the file system.
