CATGETS(P) POSIX Programmer s Manual CATGETS(P)
PROLOG 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.
NAME catgets - read a program message
SYNOPSIS #include <nl_types.h>
char *catgets(nl_catd catd, int set_id, int msg_id, const char *s);
DESCRIPTION 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.
The catgets() function need not be reentrant. A function that is not required to be reentrant is not required to be thread-safe.
RETURN VALUE If the identified message is retrieved successfully, catgets() shall return a pointer to an internal buffer area containing the null-termi- nated message string. If the call is unsuccessful for any reason, s shall be returned and errno may be set to indicate the error.
ERRORS 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.
EINTR The read operation was terminated due to the receipt of a sig- nal, and no data was transferred.
EINVAL The message catalog identified by catd is corrupted.
ENOMSG The message identified by set_id and msg_id is not in the mes- sage catalog.
The following sections are informative.
APPLICATION USAGE None.
FUTURE DIRECTIONS None.
