wn_switch_relabel_c

	status.i4.v = wn_switch_relabel_c(switch_id.i4.v, text.i1a.r, color.i4.v
					  [,on_funcs.fa.r] [,on_func_data.ga.r]
					  [,off_func.f.v] [,off_func_data.g.v])

	This routine will change the label and/or color of a switch created
	by an earlier call to wn_switch_create_c.

	switch_id	ID of desired switch
			(returned by prior call to wn_switch_create_c)
	text		null terminated switch text  (Note: For multiline
			switch labels, successive lines should be separated
			by a space which will not be displayed.)
			(If a value of NULL is passed for this argument,
			the present text will remain unchanged.)
	color		switch color (If a value of CLIB_DEFAULT_ARG is
			passed for this argument, the switch color will
			remain unchanged.)
			(constants are in 'cnsparam')
	[on_funcs]	addresses of functions to be called upon transition
			of the switch to an "on" state (one function for
			momentary or latching switches or one per switch
			for a radio switch) (default is NULL which results
			in leaving the previous "on" functions)
			(called as follows:
			 on_funcs(wid.i4.v, on_func_data.g.v, switch_data.s.r)
			 ("switch_data" is a structure of type
			  SWITCH_ACTION_DATA))
	[on_func_data]	address of data to be passed to "on_funcs"
			(default is NULL which results in leaving the previous
			 "on_funcs" data)
	[off_func]	address of function to be called when the switch
			is turned off (latching switches only) (default is NULL
			which results in leaving the previous "off" function)
			(called as follows:
			 off_func(wid.i4.v, off_func_data.g.v, switch_data.s.r)
			 ("switch_data" is a structure of type
			  SWITCH_ACTION_DATA))
	[off_func_data]	address of data to be passed to "off_func"
			(default is NULL which results in leaving the previous
			 "off_func" data)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NO_SUCH		switch does not exist
