Active Mode: The FTP client chooses a port number and sends a "PORT" command to the FTP server. If this error occurs frequently when sending data it may indicate high network latency or the inability for the remote host to read the data fast enough. In this case, the application should wait for the OnRead event to fire which indicates that more data has become available to read. WSAEFAULT 10014 Bad address.

For example, this error is returned if sendto is called with the remote address of ADDR_ANY. No more results can be returned by the WSALookupServiceNext function. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. Applications that use WSAGetOverlappedResult (with the fWait flag set to FALSE) in a polling mode to determine when an overlapped operation has completed, get this error code until the operation is

  • This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket.

This usually means the local software knows no route to reach the remote host. A connection attempt failed because the connected party did not properly respond after a period of time, or the established connection failed because the connected host has failed to respond. It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. The protocol family has not been configured into the system or no implementation for it exists.

Why is the Vitamin B complex, a "complex"? For example, the optional type SOCK_RAW might be selected in a socket call, and the implementation does not support SOCK_RAW sockets at all.
