I want to post hook the engine::GetClientConVar function but I don't know how to do it. Actually I don't really know what post hooking does... Will it receive the return value of the GetClientConVar function as a parameter or will it receive the standard params of the hooked function? I would like to change the return value if it's not like that/what it's meant to be. (I wonder if this sentence makes any sense ^^) Thanks in Advance Mysterious

Order of operations:
1. SourceHook invokes all pre hooks.
2. SourceHook invokes the original function.
3. SourceHook invokes all post hooks.

You receive the parameters of the hooked function, always (in fact the signature must be identical). In a post hook you can access the original return value with the META_RESULT_ORIG_RET() macro, and you can override the return value as normal. (Note: playing nicely with other plugins is slightly more complicated - you should really check the return status with META_RESULT_STATUS to see if the return value has been overridden, and if so, call META_RESULT_OVERRIDE_RET instead of the other macro).

Anyway, if you meant IVEngineServer::GetClientConVarValue, just be forewarned that the engine itself probably won't call this virtually. The game might though.

Hmm, that might explain why I was getting random values from META_RESULT_ORIG_RET() in a pre-hook, thanks BAIL

Silly Tsunami. You can't get a result before the function calculates a result to return. arrrrrrgh!
