我正在尝试绑定服务器套接字,以便我可以接收和侦听来自其他客户端的传入消息.但我无法绑定,它返回一个错误 – 套接字绑定失败：99.我读了它的意思,它说errno 99表明套接字不存在？有任何想法吗？谢谢

@H_403_2@UDP_socketID = socket(AF_INET,SOCK_DGRAM,0);

if (UDP_socketID < 0)

{

printf("Socket creation Failed! Error = %d\n\n",errno);

exit(0);

}

//specify server address,port and IP

bzero((char *)&serverAddr,sizeof(serverAddr));

serverAddr.sin_family = AF_INET;

serverAddr.sin_addr.s_addr = htonl(INADDR_ANY);

serverAddr.sin_port = htons(SERV_PORT);

check = inet_aton(SERVER_IP,&serverAddr.sin_addr);

if (check == 0)

printf("IP conversion error!\n\n");

start = bind(UDP_socketID,(struct sockaddr *) &serverAddr,sizeof(serverAddr));

if (start < 0) {

printf("Socket bind Failed = %d\n",errno);

exit(0);

}

else

printf("Socket bind successful!\n");

99是EADDRNOTAVAIL.这意味着(来自man bind(2))：

A nonexistent interface was requested or the requested address was not

local.

也许SERVER_IP不是您主机的IP.
