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_client  219.222.170.9 9734

arm_client

arm_client

exit
