SIGPAUSE(2)						     Linux Programmer's Manual						       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.

CONFORMING TO

       4.4BSD.	The sigpause function call appeared in 4.3BSD and is deprecated.

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.

HISTORY

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