BINDTEXTDOMAIN(3)                                            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, every software package has its  own  message
       domain. The need for calling bindtextdomain arises because packages are not always installed with the same pre-
       fix as the <libintl.h> header and the libc/libintl libraries.

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

       domainname must be a non-empty string.

       If  dirname  is  not  NULL,  the  base  directory for message catalogs belonging 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 mes-
       sage catalogs will be found.

       If dirname is NULL, the function returns the previously set base directory for domain domainname.

RETURN VALUE
       If successful, the bindtextdomain function returns the current base directory for domain domainname, after pos-
       sibly changing it. The resulting string is valid until the next bindtextdomain call for the same domainname 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 warnings in C code predating ANSI C.
