Description: Engine allows anyone to hook APIs very easily using their hooking dll.

Each hooking dll might have 3 types of exports:
1. prefixed HOOK
2. prefixed Detoured
3. hookmain (optional)

1. Whenever you want to hook some API you will put this kind of export:


Also note that inline hook will point to this procedure so this procedure
will have all of your code responsible for certain API.

2. To be able to call original API from your hook you should export also
this variable (in C/C++ it will be function pointer):

Note how variables are prefixed with "Detoured_"


Here is one example from C/C++ code:

extern "C" __declspec(dllexport) HMODULE (__stdcall *Detoured_GetModuleHandleA)(LPCTSTR modulename) = NULL;

extern "C" HMODULE __declspec(dllexport) __stdcall HOOK_kernel32_GetModuleHandleA(LPCTSTR modulename){
return Detoured_GetModuleHandleA(modulename);

Note also that this is optional, if you don't need to call orignal proc,
then you don't need this export.

Note that when working with MSVC2005 it will always screw export name for
procedures while function pointers are properly exported, so add this line
to your .def file:

HOOK_kernel32_GetModuleHandleA = _HOOK_kernel32_GetModuleHandleA@4

3. hookmain

hookmain is export which has this prototype:

void __stdcall hookmain();

This procedure will be called before program jumps to entrypoint of
target, here you may add some extra code, it isn't very useful and
all initialization you may perfrom in DllEntry, but I leave this here
just in case that you want to start your own tracer before code jmps
to entrypoint. At least that's why I'm using it.
