sigpending(2)                                                 sigpending(2)


   NAME
         sigpending - examine signals that are blocked and pending

   SYNOPSIS
         #include <signal.h>

         int sigpending(sigsett *set);

   DESCRIPTION
         The sigpending function retrieves those signals that have been sent
         to the calling process but are being blocked from delivery by the
         calling process's signal mask.  The signals are stored in the space
         pointed to by the argument set.

         sigpending fails if the following is true:

         EFAULT         The set argument points outside the process's
                        allocated address space.

   SEE ALSO
         sigaction(2), sigprocmask(2), sigsetops(3C).

   DIAGNOSTICS
         On success, sigpending returns zero.  On failure, it returns -1 and
         sets errno to indicate the error.
