Only a handful of ISO 639-3 languages are supported by Qt. Standard Malay is not one of them. Using the macrolanguage code seems fine. Not too sure what the numerusform is for a macrolanguage, but appears that wikipedia equates MS w/ "bahasa" too

#include <stdio.h>
#include "openalbridge.h"

int main (int argc, int **argv) {

    openal_init();

    openal_close();

    return 0;
}
