Linux socket网络编程基础 tcp和udp

Socket TCP网络通信编程

首先，服务器端需要做以下准备工作：

　　（1）调用socket()函数。建立socket对象，指定通信协议。

　　（2）调用bind()函数。将创建的socket对象与当前主机的某一个IP地和端口绑定。

　　（3）调用listen()函数。使socket对象处于监听状态，并设置监听队列大小。

客户端需要做以下准备工作：

　　（1）调用socket()函数。建立socket()对象，指定相同通信协议。

　　（2）应用程序可以显式的调用bind()函数为其绑定IP地址和端口，当然，也可以将这工作交给TCP/IP协议栈。

接着建立通信连接：

　　（1）客户端调用connect()函数。向服务器端发出连接请求。

　　（2）服务端监听到该请求，调用accept()函数接受请求，从而建立连接，并返回一个新的socket文件描述符专门处理该连接。

然后通信双方发送/接收数据：

　　（1）服务器端调用write()或send()函数发送数据，客户端调用read()或者recv()函数接收数据。反之客户端发送数据，服务器端接收数据。

　　（2）通信完成后，通信双方都需要调用close()或者shutdown()函数关闭socket对象。

UDP网络通信编程

 客户不与服务器建立链接，而是管使用sendto函数给服务器发送数据报，其中必须指定目的地址（即服务器地址）作为参数。类似的，服务器不接受来自客户的连接，而只管调用

revcfrom函数等待来自某个客户数据的到达。revcfrom将与所接受到的数据报一道返回客户的协议地址，因此服务器可以把响应发送给正确的客户。
