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.
