TEXTDOMAIN(3)              Library Functions ManualTEXTDOMAIN(3)NAME       textdomain - set domain for future gettext() callsSYNOPSIS       #include <libintl.h>       char * textdomain (const char * domainname);DESCRIPTION       The textdomain function sets or retrieves the current message domain.       A  message domain is a set of translatable msgid messages. Usually, ev-       ery software package has its own message domain.  The  domain  name  is       used to determine the message catalog where a translation is looked up;       it must be a non-empty string.       The current message domain is used by the gettext, ngettext  functions,       and by the dgettext, dcgettext, dngettext and dcngettext functions when       called with a NULL domainname argument.       If domainname is not NULL, the current message domain is set to domain-       name.  The  string  the function stores internally is a copy of the do-       mainname argument.       If domainname is NULL, the function returns the current message domain.RETURN VALUE       If successful, the textdomain function returns the current message  do-       main,  after  possibly changing it. The resulting string is valid until       the next textdomain call and must not be modified or freed. If a memory       allocation failure occurs, it sets errno to ENOMEM and returns NULL.ERRORS       The following error can occur, among others:       ENOMEM Not enough memory available.BUGS       The  return type ought to be const char *, but is char * to avoid warn-       ings in C code predating ANSI C.SEE ALSOgettext(3),ngettext(3),bindtextdomain(3),bind_textdomain_codeset(3)GNU gettext 0.19.8.1               May 2001TEXTDOMAIN(3)
