Winsock Returned Error Code 10050
WSAEADDRINUSE (10048) Address already in use. WSAEISCONN (10056) Socket is already connected. The ICMP message means that a router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down). WinSock description: No equivalent WinSock functions:
It looks like you are using VS2005 or newer where std::string has internal 16 chars long buffer - and exactly this buffer address was passed into gethostbyname(). WinSock description: Same as Berkeley. WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a See other suggestions under WSAECONNABORTED. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
What Is A Socket Error
The WinSock API does not provide any way to select specific name resolution protocols, server address, or record type. This usually results from trying to connect to a service that is inactive on the foreign host. after failed calls to inet_addr() or gethostbyname()), then simply test your address value for zero before you pass it to sendto(). This reset could be generated locally by the network system when it detects a connection failure, or it might be received from the remote host (in TCP terms, the remote host
User suggestions: see WSAHOST_NOT_FOUND for details. WSAEPROTOTYPE 10041 Protocol wrong type for socket. When I added a resistor to a set of christmas lights where I cut off bulbs, it gets hot. Socket Error 11004 So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET).
Will I encounter any problems as a recognizable Jew in India? Socket Error Codes Linux Berkeley description: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was supplied. WSAECONNREFUSED 10061 Connection refused. http://support.dameware.com/kb/article.aspx?ID=300058 The WSAAsyncSelect() FD_WRITE event is specifically designed to notify an application after a WSAEWOULDBLOCK error when buffer space is available again so send() or sendto() should succeed.
User suggestions: see WSAHOST_NOT_FOUND for details. Winsock Error 10054 Fix all other functions: retry the operation again later since it cannot be satisfied at this time. So, for example, if a WinSock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket() call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at WinSock functions:

WSAENOTEMPTY 10066 Directory not empty. http://www.sockets.com/err_lst1.htm With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). What Is A Socket Error User suggestions: see WSAENETUNREACH for details WinSock functions:
Achieve same random number sequence on different OS with same seed How do I amplify a 0-100mV signal to an ADC with a range from 0 to a specific reference voltage? this contact form Some WinSock implementation use these errors inappropriately, but they have a particular meaning. Check the destination address itself; is it the one you wanted to go to? Other information varies between different errors. Socket Error 10054 Connection Reset By Peer
- Are you using an optional level or socket option that may not be supported on all WinSock implementations?

- WSAEINPROGRESS 10036 Operation now in progress.
- If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address.
- The WinSock description and TCP/IP scenario contain detailed descriptions of the errors, which also describe possible cause and imply a possible remedy.
Some of these functions cannot fail, which explains their absence from the error list below. Socket Error 10061 Connection Refused As we pointed out earlier, your application should be ready to encounter any error at any time. WinSock description: Similar to Berkeley.
Not the answer you're looking for?
WSAEDESTADDRREQ 10039 Destination address required. The WinSock implementation was unable to allocate additional memory to accommodate the function request. If we modify our Winsock initialization code slightly... Socket Error 11001 the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail.
For instance, this error will occur if you try to run two applications that have FTP servers. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. Check This Out In this case, the 2nd application will fail with WSAEADDRINUSE.
WinSock description: a quick comparison to the Berkeley counterpart, and a long description of WinSock error. If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. WSANO_DATA (11004) Valid name, no data record of requested type Berkeley description: The requested name is valid, but does not have an Internet IP address at the name server. WSAEPROTONOSUPPORT (10043) Protocol not supported.
That means that on 32-bit systems, the addresses have to be multiples of 4, and on 64-bit systems, they must be multiples of 8. Detailed description (from RFC 1035, "Domain Names", by P.Mockapetris): Format error: name server was unable to interpret the query. copies what it can into your buffer) and fails the function. WinSock description: Similar to Berkeley & Microsoft C, the generic meaning is that an application passed invalid input parameter in a function call.
WinSock functions: recv(), recvfrom(), send(), sendto(), with datastream sockets only. Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. Do you have a router configured? WSAEISCONN 10056 Socket is already connected.
When it occurs, it could indicate a serious failure of your network system (i.e. In it's place, WinSock uses the error WSAENETUNREACH, exclusively. share|improve this answer answered Dec 5 '09 at 0:39 Ron Murray 111 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Berkeley description: The quota system ran out of table entries.
