Hooking & modifying WSARec

[Dody]

I successeded hooking the WSARec for read only:
I hooked the following:


INT WINAPI WSARecvHookProc(SOCKET s, LPWSABUF lpBuffers, DWORD dwBufferCount, LPDWORD lpNumberOfBytesRecvd, LPDWORD lpFlags, LPWSAOVERLAPPED lpOverlapped, LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine)



My question is how to write to the hooked buffer. I want to modify a packet with value 1 to 0
how can I rewrite the buffer with the value I want?



I am coding with c++ (VS2005)

Thanks in advance!
