6 catgets - get message from a message catalog

11 char *catgets(nl_catd catalog, int set_number, int message_number,
12 const char *message);

15 catgets() reads the message message_number, in set set_number, from the
16 message catalog identified by catalog, where catalog is a catalog
17 descriptor returned from an earlier call to catopen(3). The fourth
18 argument message points to a default message string which will be
19 returned by catgets() if the identified message catalog is not cur‐
20 rently available. The message-text is contained in an internal buffer
21 area and should be copied by the application if it is to be saved or
22 modified. The return string is always terminated with a null byte.
23
25 On success, catgets() returns a pointer to an internal buffer area con‐
26 taining the null-terminated message string. On failure, catgets()
27 returns the value message.

30 These functions are only available in libc.so.4.4.4c and above. The
31 Jan 1987 X/Open Portability Guide specifies a more subtle error return:
32 message is returned if the message catalog specified by catalog is not
33 available, while an empty string is returned when the message catalog
34 is available but does not contain the specified message. These two
35 possible error returns seem to be discarded in SUSv2 in favour of
36 always returning message.
