AFAIK, the presense of any forms of locale "aliasing" does not
comply current POSIX specifications :
string=setlocale(LC_xxx, "language_TERRITORY.Codeset");
should returns _THE_SAME_ locale name _as requested_.
Try this on "aliased" and "non aliased" locales.
(JFYI: It fails on any "aliased" locales on glibc2.)
==lct.c======
#include <stdio.h>
#include <locale.h>
#include <string.h>
main (int argc, char *argv[]) {
char * reqlcname;
char * gotlcname;
if (argc != 2){
printf("Usage: lct language[_TERRITORY[.Codeset]]\n");
exit (1);
};
reqlcname=argv[1];
printf("Trying to set LC_CTYPE=%s\n",reqlcname);
gotlcname=setlocale(LC_CTYPE, reqlcname); /* ALL MAGIK IS HERE */
if ( !gotlcname) {
printf ("There is no locale '%s' in your system.\n",reqlcname);
exit (1);
}
else {
printf("I've got LC_CTYPE=%s\n",gotlcname);
if ( strcmp(gotlcname, reqlcname))
printf("I can't set REQUIRED locale !\n");
else
printf("Great! All OK.\n");
};
}
