NAME
       ssignal(), gsignal() - software signals

SYNOPSIS
DESCRIPTION
       and  implement a software facility similar to signal(5).	 This facility
       is used by the Standard C Library to enable users to indicate the  dis‐
       position	 of  error conditions, and is also made available to users for
       their own purposes.

       Software signals made available to users are associated	with  integers
       in the inclusive range 1 through 15.  A call to associates a procedure,
       action, with the software signal sig;  the  software  signal,  sig,  is
       raised  by a call to Raising a software signal causes the action estab‐
       lished for that signal to be taken.

       The first argument to is a number identifying the type  of  signal  for
       which  an action is to be established.  The second argument defines the
       action; it is either the name of a (user-defined)  action  function  or
       one  of	the  manifest  constants  (default)  or (ignore).  returns the
       action previously established for that signal type; if  no  action  has
       been established or the signal number is illegal, returns

       raises the signal identified by its argument, sig:

	      ·	 If  an	 action	 function  has	been established for sig, that
		 action is reset to and the action function  is	 entered  with
		 argument sig.	returns the value returned to it by the action
		 function.

	      ·	 If the action for sig is returns the value  1	and  takes  no
		 other action.

	      ·	 If  the  action  for  sig is returns the value 0 and takes no
		 other action.

	      ·	 If sig has an illegal value or no action was  ever  specified
		 for sig, returns the value 0 and takes no other action.

       signal(5), thread_safety(5).

NOTES
       Some additional signals with numbers outside the range 1 through 15 are
       used by the Standard C Library to  indicate  error  conditions.	 Those
       signal numbers outside the range 1 through 15 are legal, although their
       use may interfere with the operation of the Standard C Library.
