Call this member function to get the address of the peer socket to which this socket is connected (handles IPv6 addresses).
Reference to a CString object that receives a dotted number IP address.
Reference to a UINT that stores a port.
Nonzero if the function is successful; otherwise 0, and a specific error code can be retrieved by calling GetLastError. The following errors apply to this member function:
WSANOTINITIALISED A successful AfxSocketInit must occur before using this API.
WSAENETDOWN The Windows Sockets implementation detected that the network subsystem failed.
WSAEFAULT The lpSockAddrLen argument is not large enough.
WSAEINPROGRESS A blocking Windows Sockets call is in progress.
WSAENOTCONN The socket is not connected.
WSAENOTSOCK The descriptor is not a socket.
This function is the same as CAsyncSocket::GetPeerName except that it handles IPv6 addresses as well as older protocols.
