BINDTEXTDOMAIN(3)BINDTEXTDOMAIN(3)NAMEbindtextdomain - 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_MES-
SAGES.
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; oth-
erwise 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 possi-
bly 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.
