annotate include/SDL_byteorder.h @ 885:9f6ad2286011

Date: Wed, 28 Apr 2004 16:52:41 -0400 From: "Damien A" Subject: testdyngl fix The test program you included in the latest version of SDL crashes on startup in Window (XP). The reason for this is that OpenGL functions on Windows use the __stdcall calling convention, not the C convention. Placing APIENTRY infront of the * operator solves this problem.
