说明：  linux下 ipv6协议 ping程序源码最多运行50线程 2.每个线程发送4个ICMP6包后开始接收 3.试验程序源码，多线程结构安排不一定合理，待试验验后进一步修改 4.在终端./pingipv6 IP11 1P2......即可运行程序源码 5.为单源文件，没写make，编译命令为: gcc 可直接使用。
(ping program source code under linux ipv6 protocol up to run 50 threads each thread send the four ICMP6 package to receive three test program source code, multi-threaded structural arrangement is not necessarily reasonable, upon trial experience further modification. in the terminal./pingipv6 IP11 1P2 ...... you can run the program source code for a single source file, I did not write the make, the compile command: gcc can be used directly.)
