That's an 0xE9 style inline hook for x86. This is called an inline hook or a detour and yes it's supported.
from polyhook_2_0.
I am use polyhook and crash game. (the code is exactly the same as in CCallHook)
https://github.com/sr-tream/ClassicArrow/blob/master/main.cpp#L31-L32
polyhook code:
PLH::CapstoneDisassembler dis(PLH::Mode::x86);
PLH::x86Detour detour((char*)0x00748DA3, (char*)&MainLoop, &hookPrintfTramp, dis);
detour.hook();
void CALLBACK MainLoop()
{
}
P.S: the function is even called 1 time, but then it crashes.
P.S.S: I am confused that there is 6 used in the constructor
P.S.S.S: I am setup hook in DLLMain (DLL_PROCESS_ATTACH)
I hope you can help
