if (timeout) {
signal (SIGALRM, alarm_int);
alarm (timeout) ;
}
if (setjmp (timrenv) == 0) {
retval = routine (param1, param2) ;
/* this is a normal return */
} else {
/* we come here after a timeout */
Our codebase have several places where timeouts are handled by
setjmp/longjmp as the snippet above. The alarm handler finish with a
longjmp(). This is legacy code, originally deployed on Xenix. I've
been lead to beleive that this was the only reliable way of handling
socket timeouts on that platform.
