WSASend/WSARecv hooks don't work in open-source injectable

[holly-hacker]

Definition on this line.

WSASend and WSARecv use the PASCAL calling convention, which is not supported by .NET. This may be why it doesn't work The injectable DLL that does the hooking is written in .NET, meaning there is a difference between the calling convention of the new function and the original function.

It's possible to change the calling convention of a Delegate with UnmanagedFunctionPointerAttribute, but only cdecl, fastcall, stdcall and thiscall seem to be supported.

Of course it is possible that it's due to another reason that this hook doesn't work, and maybe we'll have to switch to a different hooking method altogether.
