MinHook

A Windows API hooking library originally written by Tsuda Kageyu.

Main differences from original v1.1

• Removed boost dependency (jarredholman).
• Fixed a small bug in the GetRelativeBranchDestination function (pillbug99).
• Added the MH_RemoveHook function, which removes a hook created with the MH_CreateHook function.
• 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 to MH_EnableHook or MH_DisableHook suspends and resumes all threads.
• Made the functions MH_EnableHook and MH_DisableHook enable/disable all created hooks when the MH_ALL_HOOKS parameter 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_CreateHook function returns MH_ERROR_UNSUPPORTED_FUNCTION. This fixes an issue of hooking the LoadLibraryExW function on Windows 7 x64 (reported by Obble).
