基本功能都全了. 发上来共享下.

程序使用ACE.

ACE的简介:

http://www.cs.wustl.edu/~schmidt/ACE-overview.html

udp测试工具:

功能描述

1.纯发送功能
udp 192.168.1.22:9000 c:\bootbak.ini 将文件c:\bootbak.ini发送到192.168.1.22

2.纯接收功能
udp 9000  接收9000端口udp数据

3.转发功能
udp 9000 192.168.1.22:9000 forward 本地端口9000接收,发往192.168.1.22:900端口

4.要保存文件只需要在命令行后加 > result.txt即可.

可执行文件和源码. /Files/alantop/udp.rar


再放一个老版本 win32 sdk版本的udp

/Files/alantop/UdpDHCP.rar

2. 如何从域名获取IP地址

3. 如何从struct in_addr和struct hostent结构中获取IP地址
