dylib-mitm

This crate intended to make dynamic libs proxying easier.

Currently supported targets:

• Windows x64
• Windows x86

Important

Default calling convention is extern "C".

Dynamic libraries that export non-callable symbols (data) are not supported. It must be rare for dylibs though.

Example

Load specified dynamic library and reexport it's exports. Library must be loaded with lib_name::init() as soon as possible.

Typical code injection through d3d9 dll:

dylib_mitm::dylib_mitm!(proto_path = r"C:\Windows\system32\d3d9.dll");

pub extern "C" fn DllMain(_: *mut u8, call_reason: i32, _: *mut u8) {
    println!("Called dllmain of mitm DLL!");
    match call_reason {
        1 => unsafe { d3d9::init() },
        _ => (),
    }
}
