catgets(3) Library Functions Manual catgets(3)
catgets - get message from a message catalog
Standard C library (libc, -lc)
#include <nl_types.h>
char *catgets(nl_catd catalog, int set_number, int message_number,
const char *message);
catgets() reads the message message_number, in set set_number,
from the message catalog identified by catalog, where catalog is a
catalog descriptor returned from an earlier call to catopen(3).
The fourth argument, message, points to a default message string
which will be returned by catgets() if the identified message
catalog is not currently available. The message-text is contained
in an internal buffer area and should be copied by the application
if it is to be saved or modified. The return string is always
terminated with a null byte ('\0').
On success, catgets() returns a pointer to an internal buffer area
containing the null-terminated message string. On failure,
catgets() returns the value message.
For an explanation of the terms used in this section, see
attributes(7).

The catgets() function is available only in libc.so.4.4.4c and
above.
The Jan 1987 X/Open Portability Guide specifies a more subtle
error return: message is returned if the message catalog specified
by catalog is not available, while an empty string is returned
when the message catalog is available but does not contain the
specified message. These two possible error returns seem to be
discarded in SUSv2 in favor of always returning message.
