SIGPAUSE(3)

NAME
sigpause - atomically release blocked signals and wait for interrupt

SYNOPSIS
#include <signal.h>
int
sigpause(int sigmask);

DESCRIPTION
This interface is made obsolete by sigsuspend(2).

Sigpause() assigns sigmask to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored. Sigmask is usually 0 to indicate that no signals are to be blocked. Sigpause() always terminates by being interrupted, returning -1 with errno set to EINTR.

HISTORY
The sigpause() function call appeared in 4.2BSD and has been deprecated.
