class_get_names

	class_get_names(mask.i4.v, return_string.i1a.r)

	This routine builds a string of class names in "return_string"
	based on the contents of "mask".  If multiple bits are set in
	the mask, the named classes will be separated by spaces.
	Undefined classes return nothing, so it is possible to be
	returned a NULL string.

	mask		console class mask bits (each "ON" bit defines
	 		a class to be translated) (constants are in 'class')
	return_string	an array of characters long enough to accept the
			appended class names (will be returned NULL
			terminated) (Allow at least CONSOLE_CLASS_NAME_LEN + 1
			characters per name.)

	This function requires the following include files:

	class_h, clib_h
