CATGETS(3P) POSIX Programmer's Manual CATGETS(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
catgets — read a program message
#include <nl_types.h>
char *catgets(nl_catd catd, int set_id, int msg_id, const char *s);
The catgets() function shall attempt to read message msg_id, in set
set_id, from the message catalog identified by catd. The catd
argument is a message catalog descriptor returned from an earlier
call to catopen(). The results are undefined if catd is not a value
returned by catopen() for a message catalog still open in the
process. The s argument points to a default message string which
shall be returned by catgets() if it cannot retrieve the identified
message.
The catgets() function need not be thread-safe.
If the identified message is retrieved successfully, catgets() shall
return a pointer to an internal buffer area containing the null-
terminated message string. If the call is unsuccessful for any
reason, s shall be returned and errno shall be set to indicate the
error.
The catgets() function shall fail if:
EINTR The read operation was terminated due to the receipt of a
signal, and no data was transferred.
ENOMSG The message identified by set_id and msg_id is not in the
message catalog.
The catgets() function may fail if:
EBADF The catd argument is not a valid message catalog descriptor
open for reading.
EBADMSG
The message identified by set_id and msg_id in the specified
message catalog did not satisfy implementation-defined
security criteria.
EINVAL The message catalog identified by catd is corrupted.
