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.
