SIGPENDING(2)	    UNIX Programmer's Manual	    SIGPENDING(2)


NAME
     sigpending - get pending signals

SYNOPSIS
     #include <signal.h>

     int
     sigpending(set)
     sigset_t *set;

DESCRIPTION
     The sigpending function returns a mask of the signals pend-
     ing for delivery to 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
     A 0 value indicated that the call succeeded.  A -1 return
     value indicates an error occurred and errno is set to indi-
     cated the reason.

ERRORS
     If sigpending fails then errno will contain one of the fol-
     lowing:


     [EFAULT]		 set contains an invalid address.

SEE ALSO
     sigaction(2), sigprocmask(2)

STANDARDS
     The sigpending function is defined by IEEE Std1003.1-1988
     (``POSIX'').
