pause(2)
NAME
pause − suspend process until signal
SYNTAX
int pause()
DESCRIPTION
The pause system call suspends the calling process until it receives a signal. The signal must be one that is not currently set to be ignored by the calling process.
RETURN VALUE
If the signal causes termination of the calling process, the pause call will not return.
If the signal is caught by the calling process and if control is returned from the signal-catching function, the calling process resumes execution from the point of suspension. The pause call then returns a −1, and the global variable errno is set to EINTR. For further information about catching signals, see signal(2).
