[LWIP]在源码中查看Lwip版本号

lwip源码中版本号在文件init.h中，文件路径为LwIP\src\include\lwip

如下代码为init.h中版本号信息的宏定义，可知我是用的是2.1.2版本

/** X.x.x: Major version of the stack */
#define LWIP_VERSION_MAJOR      2
/** x.X.x: Minor version of the stack */
#define LWIP_VERSION_MINOR      1
/** x.x.X: Revision of the stack */
#define LWIP_VERSION_REVISION   2

init.h完整代码如下

#ifndef LWIP_HDR_INIT_H
#define LWIP_HDR_INIT_H

#include "lwip/opt.h"

#ifdef __cplusplus
extern "C" {
#endif
