Question

if( bind(listenfd, (struct sockaddr*)&servaddr, sizeof(servaddr)) == -1)错误是怎么回事？

memset(&servaddr, 0, sizeof(servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
servaddr.sin_port = htons(6666);

if( bind(listenfd, (struct sockaddr*)&servaddr, sizeof(servaddr)) == -1){
printf("bind socket error: %s(errno: %d)/n",strerror(errno),errno);
exit(0);
}

#include"winsock.h"

#pragma comment(lib,"WS2_32.LIB")

WSADATA ws;
WSAStartup(MAKEWORD(2,0),&ws);

if( bind(listenfd, (struct sockaddr*)&servaddr, sizeof(servaddr)) == SOCKET_ERROR)
{
printf("出错!");
}

WSACleanup();

这个是打印错误么

追答

这个是bind()函数执行出错就会提示出错
