SIGPAUSE(3) Library Functions Manual SIGPAUSE(3)

NAME

sigpauseatomically 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.
