# shithook

A c++ header only library for inline hooking. Supports x86_64, x86, and arm. Small, simple, and easily detected :)

# usage

Installing the hook/Init.
```cpp
__attribute__((noinline)) // very important that this is not inline!
FILE* hook_test(const char* filename, const char* open_type)
{
    std::printf("> filename = %s\n", filename);
    std::printf("> open type = %s\n", open_type);
    std::getchar();
    
    return hook::get_func(&fopen)(filename, open_type);
}

hook::make_hook(&fopen, &hook_test);
```

### Calling Original 

`hook::get_func` is templated so that you can pass a function pointer I.E `&fopen` and the returned pointer will be of that type.

```cpp
return hook::get_func(&fopen)(filename, open_type); // returned value is of type: FILE* (*)(const char*, const char*);
```

### Disable Hook

```cpp
hook::disable(&fopen);
```

### Enable Hook

```cpp
hook::enable(&fopen);
```
