SIGPAUSE(2)

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.

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