2.4.16: sigtimedwait - Synchronously Accept a Signal with Timeout

CALLING SEQUENCE:

#include <signal.h>

int sigtimedwait(
  const sigset_t        *set,
  siginfo_t             *info,
  const struct timespec *timeout
);

STATUS CODES:

EAGAIN: Timed out while waiting for the specified signal set.
EINVAL: Nanoseconds field of the timeout argument is invalid.
EINTR: Signal interrupted this function.

DESCRIPTION:

This function selects a pending signal based on the set specified in set, atomically clears it from the set of pending signals, and returns information about that signal in info. The calling thread will block up to timeout waiting for the signal to arrive.

NOTES:

If timeout is NULL, then the calling thread will wait forever for the specified signal set.
