     NAME
          sigpending - Examine pending signals.

     SYNOPSIS
          #include <signal.h>

          int sigpending (set)
          sigset_t *set;

     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.

     RETURNS
          Upon successful completion a value of zero is returned.
          Otherwise, a value of -1 is returned and errno is set to
          indicate the error.

     ERRORS
          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.

     STANDARDS
          The EFAULT error will be generated if the argument set
          specifies an invalid error of the calling process's address
          space, or an address area which does not have write access.
