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.

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.

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.
