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

 1 BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
 2 {
 3     printf("hModule.%p lpReserved.%p 
", hModule, lpReserved);
 4 
 5     switch (ul_reason_for_call)
 6     {
 7         case DLL_PROCESS_ATTACH:
 8             printf("Process attach. 
");
 9             break;
10 
11         case DLL_PROCESS_DETACH:
12             printf("Process detach. 
");
13             break;
14 
15         case DLL_THREAD_ATTACH:
16             printf("Thread attach. 
");
17             break;
18 
19         case DLL_THREAD_DETACH:
20             printf("Thread detach. 
");
21             break;
22     }
23 
24     return (TRUE);
25 }
