SOCKET slisten = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); 1. 创建完毕后,判断socket是否创建成功,不成功返回-1: if (slisten == -1) { printf("socket error !"); return 0; } 1. 2.4 IP绑定 接下来开始绑定监听的IP地址。创建sockaddr_in结构体变量。
(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...
