CrossHook

A fork of the MinHook library, with support for POSIX and MacOS X

No previous behavior should have changed, besides the lack of thread suspension and context changing in POSIX, which will probably never be added, looking at the state of their API. However, there is an assumption being made in the function GetMemoryBlock, located at buffer.c, that is, mmap should use the address hint given to it to allocate a block of memory close to the origin address.

    • Simplified the overall code base to make it more readable and maintainable.
    • Changed the license from 3-clause to 2-clause BSD License.

  • v1.2 - 28 Sep 2013

    • 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).

  • v1.1 - 26 Nov 2009

    • Changed the interface to create a hook and a trampoline function in one go to prevent the detour function from being called before the trampoline function is created. (reported by xliqz)
    • Shortened the function names from MinHook_* to MH_* to make them handier.

  • v1.0 - 22 Nov 2009

    • Initial release.
