BINDTEXTDOMAIN(3) Library Functions Manual BINDTEXTDOMAIN(3)
bindtextdomain - set directory containing message catalogs
#include <libintl.h>
char * bindtextdomain (const char * domainname, const char * dirname);
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.
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.
The following error can occur, among others:
ENOMEM Not enough memory available.
The return type ought to be const char *, but is char * to avoid
warnings in C code predating ANSI C.
