当需要绑定IPv6时,可以使用bind()函数,并且参数中的sockaddr结构体类型应为struct sockaddr_in6。例如: intsockfd=socket(AF_INET6,SOCK_STREAM,0);// 创建IPv6套接字 structsockaddr_in6 addr;// IPv6地址结构体 memset(&addr,0,sizeof(addr));// 清空结构体 // 填充IPv6地址信息 addr.sin6_family=AF...
struct sockaddr支持所有网域，如果用ipv4网域，需要强制转换成struct sockaddr_in！struct sockaddr_in { ...struct in_addr sin_addr;};
intmain(void) { char*token; charbuf1[16]; charbuf2[4][4]; charbuf3[16]; inti=0; structsockaddr_inaddr; memset(buf1,0,16); memset(buf2,0,16); memset(buf3,0,16); //buf = inet_ntoa(sin_dest.sin_addr); //sprintf(buf1, "%s", inet_ntoa(sin_dest.sin_addr)); sprintf(b...

一般创建和部署套接字的步骤如下： import socket s = socket.socket(socket.AF_INET, socket.SOCK_D...
