SIGPAUSE(3)						   BSD Library Functions Manual 					       SIGPAUSE(3)

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).

     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 4.2BSD and has been deprecated.
