catgets(3) Library Functions Manual catgets(3)
NAME
catgets - get message from a message catalog
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <nl_types.h>
char *catgets(nl_catd catalog, int set_number, int message_number,
const char *message);
DESCRIPTION
catgets() reads the message message_number, in set set_number, from the
message catalog identified by catalog, where catalog is a catalog de-
scriptor returned from an earlier call to catopen(3). The fourth argu-
ment, message, points to a default message string which will be returned
by catgets() if the identified message catalog is not currently avail-
able. 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').
RETURN VALUE
On success, catgets() returns a pointer to an internal buffer area con-
taining the null-terminated message string. On failure, catgets() re-
turns the value message.

STANDARDS

HISTORY
POSIX.1-2001.
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 re-
turn: message is returned if the message catalog specified by catalog is
not available, while an empty string is returned when the message cata-
log 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.
