Function

pause invokes the pause callable service to suspend execution of the calling thread until delivery of a signal that either executes a signal-catching function or ends the thread. See Using the REXX signal services for more information.

Usage notes

1. A thread that calls pause does not resume processing until a signal is delivered with an action to either process a signal-handling function or end the thread. Some signals can be blocked by the thread's signal mask; see sigprocmask for details.
2. If an incoming unblocked signal ends the thread, pause never returns to the caller.
3. A return code is set when any failures are encountered that prevent this function from completing successfully.
