SOCKADDR 中如何填写IP和端口号进去？（作为CAsyncSocket::Connect的参数）

Question

如题

Answer 1

SOCKADDR_IN addr
addr.sin_family = AF_INET;
addr.sin_addr.S_un.S_addr = inet_addr(m_IPAddress);
addr.sin_port = htons(m_Port);

Answer 2

先创建 SOCKADDR_IN结构的变量
像楼上这样赋值后，在传递给Connect函数时作类型转换即可
Conncet(...,(SOCKADDR)addr,sizeof(addr));

Answer 3

//server------------------------------------------------ 
SOCKADDR_IN m_ServerAddr;
m_ServerAddr.sin_family = AF_INET;
m_ServerAddr.sin_addr.s_addr = htonl(INADDR_ANY);
m_ServerAddr.sin_port = htons(m_uPort);
// client---------------------------------------------
SOCKADDR_IN  m_ClientAddr;
LPHOSTENT lpHost;
lpHost = gethostbyname(pszServer);//(pszServer(LPCTSTR)is server's name)
if(lpHost == NULL) return FALSE;
m_ClientAddr.sin_family = AF_INET;
m_ClientAddr.sin_addr.s_addr = *((u_long FAR *)(lpHost->h_addr));
m_ClientAddr.sin_port=htons(m_uPort);
