Thanks for your quick response. This makes perfect sense.
I bit the bullet and added a new function to callfunc_x86.cpp 'CallSTDCallFunction' as well as the appropriate flags (#define asCALL_STDCALL 4) and updated the declaration validation in RegisterGlobalFunction.
The function I added was basically a clone of the CDecl function with the only modification really being the removal of the argument pop -the modification of the ESP register-.
This now appears to work, and there are no apparent crashes when calling __stdcall functions, but is it really this easy?
Really, I'm just looking for clarification that the only difference between calling __cdecl and __stdcall functions is that we don't pop the arguments from the stack at the end using:
add esp, paramSize
I'm probably being over optimistic and I'm actually probably going to kill the OS in the process doing this hehe :).
(Update: Doh, didn't refresh either before posting. If that is the case and the implicit this pointer is the only difference between stdcall and thiscall, then hopefully simply removing that line should do the trick. If it is, would you like me to send you the changes to save you having to re-implement it, or are you good to go?)
Thanks in advance,
