       catgets - get message from a message catalog

       #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 cur‐
       rently 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

       On success, catgets() returns a pointer to an internal buffer area con‐
       taining the null-terminated  message  string.   On  failure,  catgets()
       returns the value message.


       These  functions	 are  available only in 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.
