print ';'
print '; Module definition file for Mesa (OPENGL32.DLL)'
print ';'
print '; Note: The OpenGL functions use the STDCALL'
print '; function calling convention. Microsoft\'s'
print '; OPENGL32 uses this convention and so must the'
print '; Mesa OPENGL32 so that the Mesa DLL can be used'
print '; as a drop-in replacement.'
print ';'
print '; The linker exports STDCALL entry points with'
print '; \'decorated\' names; e.g., _glBegin@0, where the'
print '; trailing number is the number of bytes of '
print '; parameter data pushed onto the stack. The'
print '; callee is responsible for popping this data'
print '; off the stack, usually via a RETF n instruction.'
print ';'
print '; However, the Microsoft OPENGL32.DLL does not export'
print '; the decorated names, even though the calling convention'
print '; is STDCALL. So, this module definition file is'
print '; needed to force the Mesa OPENGL32.DLL to export the'
print '; symbols in the same manner as the Microsoft DLL.'
print '; Were it not for this problem, this file would not'
print '; be needed (for the gl* functions) since the entry'
print '; points are compiled with dllexport declspec.'
print ';'
print '; However, this file is still needed to export "internal"'
print '; Mesa symbols for the benefit of the OSMESA32.DLL.'
