NAME
       sigpending - examine pending signals

SYNOPSIS
       #include <signal.h>

       int sigpending (set)
       sigsett *set;

   where:
       set    A structure to which the list of signals are to be written

DESCRIPTION
       The sigpending() function shall store the set of signals that are
       blocked from delivery and pending for the calling process, in the
       space pointed to by the argument set.

RETURN VALUE
       0      Successful completion.

       -1     An error occurred.  errno is set to indicate the error.

       This standard does not specify any error conditions that are required
       to be detected for the sigpending() function.  Some errors may be
       detected under implementation-defined conditions.
