client hook [source engine]
im trying to write a simple JMP (E9) hook for a source engine game so i can log the parameters passed to a certain function. here is my source (MASM),
anyways it dosent seem to do anything.
i call it like this:
Code:
hook proc from:dword, to:dword push 40h push 1000h push 4h push 0 call VirtualAlloc mov [oldProt], eax push [oldProt] push 40h push 5h push from call VirtualProtect push eax push edx mov edx, from mov eax, to sub eax, edx sub eax, 5 mov dword ptr ds:[from], 0E9h inc from mov dword ptr ds:[from], eax pop edx pop eax ret 8 hook endp
i call it like this:
Code:
push 605AB298 lea eax, newfunc push eax
