NAMEcatgets — read a program message
SYNOPSIS#include <nl_types.h>
char *catgets(nl_catd catd, int set_id, int msg_id, const char *s);
DESCRIPTIONThe 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.
RETURN VALUEIf 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.
ERRORSThe 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. The following sections are informative.
