wn_text_size_in_world_coordinates_c

	status.i4.v = wn_text_size_in_world_coordinates_c(window_id.i4.v,
							  size.i4.v,
							  height.r4.r,
							  width.r4.r)

	This routine returns the size of a character in world coordinates.

	window_id	window ID returned by a previous call to wn_view(_c)
			(If a value of CLIB_DEFAULT_ARG is passed for this
			 argument, scaling for the currently active window
			 will be used.)
	size		text size (Note: Valid values are from WN_TEXT_MIN_SIZE
			to WN_TEXT_MAX_SIZE.)  (If a value of CLIB_DEFAULT_ARG
			is passed for this argument, the routine will return
			the size of the presently selected font.)
	height		returned character height in world coordinates
	width		returned character width in world coordinates

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid text size

	This function requires the following include files:

	cbslib_h
