SIGPENDING(2)		      System Calls Manual		 SIGPENDING(2)

NAME
       sigpending -- get pending signals

LIBRARY
       Standard	C Library (libc, -lc)

SYNOPSIS
       #include	<signal.h>

       int
       sigpending(sigset_t *set);

DESCRIPTION
       The  sigpending() system	call returns a mask of the signals pending for
       delivery	to the calling thread or the calling process in	 the  location
       indicated  by  set.   Signals may be pending because they are currently
       masked, or transiently before delivery (although	the latter case	is not
       normally	detectable).

RETURN VALUES
       The sigpending()	function returns the value 0 if	successful;  otherwise
       the  value -1 is	returned and the global	variable errno is set to indi-
       cate the	error.

ERRORS
       The sigpending()	system call will fail if:

       [EFAULT]		  The set argument specified an	invalid	address.

SEE ALSO
       sigaction(2), sigprocmask(2), sigsuspend(2), sigsetops(3)

STANDARDS
       The  sigpending()  system  call	is  expected  to  conform  to  ISO/IEC
       9945-1:1990 ("POSIX.1").
