Weblwip是tcp/ip协议栈的一种实现。lwip的主要目的是减少存储器利用量和代码尺寸,使 lwip适合应用于小的、资源有限的处理器如嵌入式系统。为了减少处理器和存储器要求,lwip 可以通过不需任何数据拷贝的api进行裁减。 本文叙述了lwip的设计与实现。叙述了协议 ... WebIf someone can explain how to use tcp_recved and what it means for storage management, I'll document it at lwip.wikia.com. I don't have the authority to update api/api_msg.c.

Weblwip可以移植到操作系统上,也可以在无操作系统的情况下独立运行。lwip tcp/ip实现的重点是在保持tcp协议主要功能的基础上减少对ram的占用,一般它只需要几十k的ram和40k左右的rom就可以运行,这使lwip协议栈适合在低端嵌入式系统中使用。 lwip的特性如下: Weblwip学习笔记2) sys_thread_new sys_arch_timeouts 相关的三个全局变量如下 struct sys_timeouts lwip_timeouts[LWIP...
