Name

sigpause - atomically release blocked signals and wait for interrupt

Library

Standard C Library (libc, -lc)

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
