如果大家玩过 C++ 的话,应该知道 C++ 的 dll 会有一个 DllMain 方法,它的意义和 Main 方法一致,代码骨架图如下:
// dllmain.cpp : Defines the entry point for the DLL application.
#include "pch.h"
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
