SIGPAUSE(3)                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.

SEE ALSO
     kill(2), sigaction(2), sigprocmask(2), sigsuspend(2), sigblock(3),
     sigvec(3)

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