Windows常见宏的使用

WIN32_LEAN_AND_MEAN


1.  参考资料:https://msdn.microsoft.com/en-us/library/windows/desktop/aa383745(v=vs.85).aspx

2.  使用说明:

       You can reduce the size of the Windows header files by excluding some of the less common API declarations as follows:

       • Define WIN32_LEAN_AND_MEAN to exclude APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

       通常我们在开发windows程序的时候,贪图省事会直接包含"windows.h"头文件,但是其实该头文件中很多的API是不需要使用到的。可以定义WIN32_LEAN_AND_MEAN宏来减小windows包含头的大小:

#ifdef _WINDOWS_                                    // windows

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#undef  WIN32_LEAN_AND_MEAN

#else                                               // linux

#endif
