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 sig);

DESCRIPTION
     This interface is made obsolete by sigsuspend(2).

     Sigpause() assigns sig to the set of masked signals and then waits for a signal to arrive; on return
     the set of masked signals is restored.  Sig is usually 0, indicating that no signals are to be blocked.
     Sigpause() always terminates by being interrupted, returning -1 with errno set to EINTR.

COMPATIBILITY
     sigpause() now takes a signal value and not a mask.  This often appears as a hang in sigpause$UNIX2003
     or with sigpause() returning with errno set to EINVAL.  Use sigsuspend() with signal masks.

SEE ALSO
     kill(2), sigaction(2), sigblock(2), sigprocmask(2), sigsuspend(2), sigvec(2)

HISTORY
     The sigpause() function call appeared in 4.2BSD and has been deprecated.

BSD                              June 2, 1993                              BSD
