retour-utils

该库旨在帮助使用retour crate创建转向。如果你创建了很多转向，这会非常繁琐，所以这个库添加了一些辅助函数和宏，以大大简化/简化流程。它适用于Unix和Windows。

示例

use retour_utils::hook_module;

#[hook_module("lua52.dll")]
mod lua {
    // #[hook_module] will create this
    // const MODULE_NAME: &str = "lua52.dll"
    // and
    // pub unsafe init_detours() -> crate::Result<()> {..}
    // which will initialize all the StaticDetours generated by the macro inside this module

    #[allow(non_camel_case_types)]
    type lua_State = ();
    #[allow(non_camel_case_types)]
    type lua_Alloc = ();
    
    // Creates a StaticDetour called Lua_newstate with the same function type as our function 
    // (minus abi/unsafe to work with retour crate)
    #[hook(unsafe extern "C" Lua_newstate, symbol = "Lua_newstate")]
    pub fn newstate(f: *mut lua_Alloc, ud: *mut std::ffi::c_void) -> *mut lua_State {
        unsafe {
            Lua_newstate.call(f, ud)
        }
    }
    // More lua hooks
}


// #[hook_module] creates a `init_hooks` function that initializes and enables all the hooks
lua::init_hooks().unwrap()

目前处于早期阶段，一些明显粗糙的区域

• 尚未提供文档
• 宏和函数的命名可能为了一致性和清晰性而改变
