已经添加头文件路径了,但编译时总是出现..\lwip-1.4.1\lwip-1.4.1\src\core%udp.c(49): error: #5: cannot open source input file "lwip/opt.h": No such fil ...
// PRINT(“ lwip task prio out of range ! error! ”); } } 从代码中可以看出tcpip_thread应该是最先创建的。 2.3 Lwip中的定时事件 在tcp/ip协议中很多时候都要用到定时,定时的实现也是tcp/ip协议栈中一个重要的部分.lwip中定时事件的数据结构如下。
