.TH CATGETS 3 1998-08-09 "" "Linux Programmer's Manual"
|
|
.SH NAME
|
|
catgets \- get message from a message catalog
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <nl_types.h>
|
|
|
|
.BI "char *catgets(nl_catd " catalog ", int " set_number \
|
|
", int " message_number ,
|
|
.BI " const char *" message );
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.BR catgets ()
|
|
reads the message
|
|
.IR message_number ,
|
|
in set
|
|
.IR set_number ,
|
|
from the message catalog identified by
|
|
.IR catalog ,
|
|
where
|
|
.I catalog
|
|
is a catalog descriptor returned from an earlier call to
|
|
.BR catopen (3).
|
|
The fourth argument
|
|
.I message
|
|
points to a default message string which will be returned by
|
|
.BR catgets ()
|
|
if the identified message catalog is not currently available.
|
|
The
|
|
message-text is contained in an internal buffer area and should be copied by
|
|
the application if it is to be saved or modified.
|
|
The return string is
|
|
always terminated with a null byte.
|
|
.SH "RETURN VALUE"
|
|
.LP
|
|
On success,
|
|
.BR catgets ()
|
|
returns a pointer to an internal buffer area
|
|
containing the null-terminated message string.
|
|
On failure,
|
|
.BR catgets ()
|
|
returns the value
|
|
.IR message .
|
|
.SH "CONFORMING TO"
|
|
POSIX.1-2001.
|
|
.SH NOTES
|
|
These functions are only available in libc.so.4.4.4c and above.
|
|
The Jan 1987 X/Open Portability Guide specifies a more subtle
|
|
error return:
|
|
.I message
|
|
is returned if the message catalog specified by
|
|
.I catalog
|
|
is not available, while an empty string is returned
|
|
when the message catalog is available but does not contain
|
|
the specified message.
|
|
These two possible error returns seem to be discarded in SUSv2
|
|
in favor of always returning
|
|
.IR message .
