#define _UNIX

int main(int argc, char** argv)
{
        char cmd[128];
        char buf[128];
        FILE* fp = NULL;
#if defined(_UNIX)
        sprintf(cmd, "which %s > my.path", argv[0]);
#else
        sprintf(cmd, "where %s > my.path", argv[0]);
#endif
        system(cmd);
        fp = fopen("my.path", "r");
        fgets(buf, sizeof(buf), fp);
        fclose(fp);

        printf("full path: %s\n", buf);
        unlink("my.path");

        return 0;
}
