catgets: read a program message
PROLOGThis 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
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 s argument points to a default message string which shall be returned by catgets() if it cannot retrieve the identified message.
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 may be set to indicate the error.
The catgets() function may fail if:
- The catd argument is not a valid message catalog descriptor open for reading.
- The message identified by set_id and msg_id in the specified message catalog did not satisfy implementation-defined security criteria.
- The read operation was terminated due to the receipt of a signal, and no data was transferred.
- The message catalog identified by catd is corrupted.
The message identified by set_id and msg_id is not in
the message catalog.
