网络的 Socket数据传输是一种特殊的I/O,Socket也是一种文件描述符。Socket也具有一个类似于打开文件的函数调用Socket(),该函数返回一个整型的Socket描述符,随后的连接建立、数据传输等操作都是通过该Socket实现的。常用的Socket类型有两种:流式Socket (SOCK_STREAM)和数据报式Socket(SOCK_DGRAM)。流式是一种面向连接...

(1) int socket(AF_INET, SOCK_DGRAM, 0); 创建udp socket,返回套接字描述符,UDP协议建立套接字的方式同TCP方式一样,使用socket()函数,只不过协议的类型使用SOCK_DGRAM,而不是SOCK_STREAM。 (2) int sendto(int sockfd, const void *data, int data_len, unsigned int flags, struct sockaddr *remaddr...
