image_matchstorage(3)		 Arcan Lua API		 image_matchstorage(3)

NAME
       image_matchstorage - test if two	vids share the same underlying storage

SYNOPSIS
       true or false
       image_matchstorage( v1, v2 )

DESCRIPTION
       This  function  can be used to determine	if two vids share the same un-
       derlying	backing	store. This can	be helpful in cases  where  one	 might
       need  transition	 based	on  visual properties that are inherent	to the
       backing store, as there are no strong equality tests for	 regular  vids
       as they are all treated as unique.

EXAMPLE
       function	image_matchstorage0()
	     a = fill_surface(32, 32, 0, 255, 0);
	     c = fill_surface(32, 32, 255, 0, 0);
	     b = null_surface(32, 32);
	     image_sharestorage(a, b);
	     assert(image_matchstorage(a, b) ==	true);
	     assert(image_matchstorage(a, c) ==	false);
	     image_sharestorage(a, c);
	     assert(image_matchstorage(a, c) ==	true);
       end
