catgets(3p)
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-terminated 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.
