Dll学习笔记

1、DLL有静态调用和动态调用两种被使用的方式；

2、DLL也有个入口函数

BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    printf("hModule.%p lpReserved.%p 
", hModule, lpReserved);

    switch (ul_reason_for_call)
    {
        case DLL_PROCESS_ATTACH:
            printf("Process attach. 
");
            break;

        case DLL_PROCESS_DETACH:
            printf("Process detach. 
");
            break;

        case DLL_THREAD_ATTACH:
            printf("Thread attach. 
");
            break;

        case DLL_THREAD_DETACH:
            printf("Thread detach. 
");
            break;
    }

    return (TRUE);
}
