status.i4.v = window_refresh_c(window_id.i2.v [,whole.i4.v])

	This routine redraws the window indicated by "window_id".  This
	allows one to repaint an exposed window.  If the argument "whole"
	is specified and has a value of TRUE, the whole window will be
	redrawn.  Otherwise, only the portion most recently exposed
	will be redrawn.

	[whole]		redrawing information flag
			(TRUE -> redraw entire window,
			 FALSE -> redraw exposed portion only (default))

	This function returns ACNET status values as follows:
