[Mesa3d-dev] Mesa and it's inner functions

[Andrew R. <and...@uc...>]

Dear All,
  Ive just come over from the DRI devel list. I've been looking at providing 
an SMP dispatch layer to Mesa to provide a means by which even if a client is 
not multithreaded  you can still get the whole process running ~2 as fast. I 
have'nt got the concentration to enumerate exactly how it works as ive been 
up ~all~ night coding. :)
  Anyway I need some way to hook a set of dummy functions into mesa so that 
the client thinks the real openGL routine has been called without breaking 
the ABI (that I assume exists in Mesa). I can quite happily using the 
_mesa_<function-name> and _tnl_<function-name> but they don't cover the whole 
API. I need to know where the other functions are. 
  If anyone has a better idea of how to hook a set of routines info mesa 
without breaking the ABI I would like to know. I know that you have some sort 
of override layer thing. How does that work? Does it alow me to get my 
routines called without knackering the ABI, but does mesa then call the 
original layer or is that my responibility? If anyone can tell me I would be 
greatful.

	Thanks
		Andy
