BINDTEXTDOMAIN(3)     DragonFly 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,
       every 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
       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 message 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 possibly 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.
