SIGPAUSE(2) BSD System Calls Manual SIGPAUSE(2)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).
The sigpause() function 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. The sigmask argument is usually 0 to indicate that no signals
are to be blocked. The sigpause() function always terminates by being
interrupted, returning -1 with errno set to EINTR
