Hello!
I'm having a strange problem experimenting. I thought, that by using
setlocale(LC_ALL, NULL) I will get whatever the current setting for
LANG (or LC_ALL) is in the environment. But as this simple program
illustrates, it is not the case:
#include <locale.h>
#include <stdio.h>
int main(int argc, char *argv[]) {
char *locale;
unsigned char b = argv[argc-1][0];
locale = setlocale(LC_ALL, NULL);
printf("In %s ``%c'' (%x) is %san alpha\n", locale, b, b,
isalpha(b) ? "" : "not ");
}
env LANG=ru_SU.KOI8-R ./t l
In C ``l'' (6c) is an alpha
env LANG=ru_SU.KOI8-R ./t Ë
In C ``Ë'' (cb) is not an alpha
env LANG=nl_NL.ISO_8859-1 ./t l
In C ``l'' (6c) is an alpha
How do I make force my C-program use the right locale? I could do
something like:
setlocale(LC_ALL, getenv("LANG"))
but is not that what specifying NULL is supposed to do?
Thanks!
