SIGPAUSE(2)		 DragonFly 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

The sigpause() function appeared in 4.2BSD and has been deprecated. DragonFly 3.7 June 2, 1993 DragonFly 3.7
