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
