NAME
       sigemptyset(),  sigfillset(), sigaddset(), sigdelset(), sigismember() -
       initialize, manipulate, and test signal sets

SYNOPSIS
DESCRIPTION
       initializes the signal set pointed to by set, to	 exclude  all  signals
       supported by HP-UX.

       initializes  the	 signal	 set pointed to by set, to include all signals
       supported by HP-UX.

       Applications must call either or at least once for each object of  type
       before  using  that object for anything else, including cases where the
       object is returned from a function (for example, the oset argument to —
       see sigprocmask(2)).

       adds the signal specified by signo to the signal set pointed to by set.

       deletes the signal specified by signo from the signal set pointed to by
       set.

       tests whether the signal specified by signo is a member of  the	signal
       set pointed to by set.

RETURN VALUE
       Upon  successful completion, returns a value of 1 if the specified sig‐
       nal is a member of the specified set, or a value of 0  if  it  is  not.
       The  other  functions  return  a value of 0 upon successful completion.
       For all of the above functions, if an error is detected, a value of  −1
       is returned and is set to indicate the error.

ERRORS
       and fail if the following is true:

	      [EINVAL]	     The value of the signo argument is out of range.

WARNINGS
       The  above  functions do not detect a bad address passed in for the set
       argument.  A segmentation fault is the most likely result.
