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.

CONFORMING TO

4.4BSD. The sigpause function call appeared in 4.3BSD and is deprecated.
