This fork adds supports for a function being hooked multiple times from one minhook instance, by different modules. This means that different DLLs can hook the same functions with no collisions. Hook disabling may not work, completely untested.
This branch supports hooking the same function from multiple instances of MinHook. In addition to the new enhancement, it has a couple of new limitations:
- The original function pointer, returned from
MH_CreateHook, can only be called when the hook is enabled. - The
MH_Initialize,MH_Uninitializefunctions are not thread safe anymore. - A mutex object is used for synchronization, and thus a new error code was introduced,
MH_ERROR_MUTEX_FAILURE.
You can see a simple demo here.

I need some funds to continue developing this library. All contributions gratefully accepted.

-
v1.2 - 28 Sep 2013
- Removed boost dependency (jarredholman).
- Fixed a small bug in the GetRelativeBranchDestination function (pillbug99).
- Added the
MH_RemoveHookfunction, which removes a hook created with theMH_CreateHookfunction. - Added the following functions to enable or disable multiple hooks in one go:
MH_QueueEnableHook,MH_QueueDisableHook,MH_ApplyQueued. This is the preferred way of handling multiple hooks as every call toMH_EnableHookorMH_DisableHooksuspends and resumes all threads. - Made the functions
MH_EnableHookandMH_DisableHookenable/disable all created hooks when theMH_ALL_HOOKSparameter is passed. This, too, is an efficient way of handling multiple hooks. - If the target function is too small to be patched with a jump, MinHook tries to place the jump above the function. If that fails as well, the
MH_CreateHookfunction returnsMH_ERROR_UNSUPPORTED_FUNCTION. This fixes an issue of hooking the LoadLibraryExW function on Windows 7 x64 (reported by Obble).
-
v1.1 - 26 Nov 2009

MinHook_*toMH_*to make them handier.
-
v1.0 - 22 Nov 2009
- Initial release.
