BINDTEXTDOMAIN(3)          Library Functions Manual          BINDTEXTDOMAIN(3)

NAME
       bindtextdomain - set directory containing message catalogs

SYNOPSIS
       #include <libintl.h>

       char * bindtextdomain (const char * domainname, const char * dirname);

DESCRIPTION
       The  bindtextdomain  function  sets the base directory of the hierarchy
       containing message catalogs for a given message domain.

       A message domain is a set of translatable msgid messages. Usually,  ev-
       ery  software  package has its own message domain. The need for calling
       bindtextdomain arises because packages are not  always  installed  with
       the  same  prefix  as  the  <libintl.h> header and the libc/libintl li-
       braries.

       Message catalogs will be expected at the pathnames dirname/locale/cate-
       gory/domainname.mo, where locale is a locale name and category is a lo-
       cale facet such as LC_MESSAGES.

       domainname must be a non-empty string.

       If dirname is not NULL, the base directory for message catalogs belong-
       ing  to  domain domainname is set to dirname. The function makes copies
       of the argument strings as needed. If the program wishes  to  call  the
       chdir  function,  it is important that dirname be an absolute pathname;
       otherwise it cannot be guaranteed that the  message  catalogs  will  be
       found.

       If dirname is NULL, the function returns the previously set base direc-
       tory for domain domainname.

RETURN VALUE
       If successful, the bindtextdomain function returns the current base di-
       rectory  for domain domainname, after possibly changing it. The result-
       ing string is valid until the next bindtextdomain call for the same do-
       mainname  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.
