Как определить функцию dllmain в ржавчине Cdylib? ⇐ C++

[Anonymous]

Есть ли особый способ определить функцию dllmain в ржавчине? Я попробовал это: < /p>
use winapi::shared::ntdef::*;
use winapi::um::winnt::DLL_PROCESS_ATTACH;
use winapi::shared::minwindef::*;
use std::*;

#[no_mangle]
extern "stdcall" fn DllMain(hInstDll: HINSTANCE, fdwReason: DWORD, lpvReserved: LPVOID){
if fdwReason == DLL_PROCESS_ATTACH {

}
}

Но, кажется, Windows не называется функцией, когда DLL прикреплен к процессу?`error: linking with 'link.exe' failed: exit code: 1120
