Single-header, minimalistic, cross-platform hook library written in pure C for x86-64 based systems.
While other well-written libraries that do exactly the same already exist, I wanted to have something simple that would not use an entire disassembler engine which can sometimes be painful to include in a project.
Pros of this library:
- Written in pure C
- No dependencies (no full disassembler engine)
- Single header
- Works in both kernelmode/usermode
- Cross-platform (Windows/Linux/EFI)
- Easily portable (3 functions to allocate/free/protect memory that are platform specific)
Cons of this library:
- Breaks when a function starts with unsupported instructions (ex. AVX)
Include the header file in your project. Initialise hook structure by calling CreateHook. Perform the actual hook by calling EnableHook and optionally revert the hook with a call to DisableHook.
HookInformation info = CreateHook((void*)&FunctionToHook, (void*)&FunctionToCall);
int status = EnableHook(&info);
if (!status)
return;
// Call the original function with info.Trampoline
FunctionToHook(10, 20);
DisableHook(&info)
