编译服务器端程序pthread_server.c：
$gcc pthread_server.c –o server –lpthread
编译客户端程序pthread_client.c:
$gcc pthread_client.c –o client
编译在开发板上跑的客户端程序：
$arm-linux-gcc client.c –o arm_client
先启动服务器端的程序server:
$./server
打开另一个终端，启动客户端的程序client:
$./client 127.0.0.1 9734
把arm_client放到开发板上，启动arm_client:
$./arm_client 219.222.170.9 9734
结果:
服务器端：
tongs@tong's-desktop:~/c_c++_program/sock_inet_comm2$ ./server
server waiting for connect
receive from client is client
receive from client is client
receive from client is arm_client
receive from client is arm_client
客户端：
tongs@tong's-desktop:~/c_c++_program/sock_inet_comm2$ ./client 127.0.0.1 9734
client
client
exit
开发板服务器端
[/mnt/yaffs/nfs_share/sock_tcp/thread_socket]./arm_client219.222.170.9 9734
arm_client
arm_client
exit
