Kinda buggy. :)
int fd, status;
char *template = strdup("/tmp/mumbleXXXXXXXX");
if (template == NULL)
/* ERROR */
fd = mkstemp(template);
if (fd == -1) {
free(template);
/* ERROR */
}
asprintf(cmd, "prog > %s", template);
status = system(cmd);
unlink(template);
free(cmd);
free(template);
close(fd);
/* if normal exit, return true if exit code was 0 (success) */
return (WIFEXITED(status) ? WEXITSTATUS(status) == EXIT_SUCCESS : 0);
