Can you ping that hostname? Browse other questions tagged c++ windows winsock or ask your own question. User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. WSA_QOS_POLICY_FAILURE 11011 QoS policy failure. http://itechnologysolutionsllc.com/socket-error/winsock-wsa-error-codes.php

WinSock functions: WSAEACCES (10013) Permission denied. WSAEPROVIDERFAILEDINIT 10106 Service provider failed to initialize. This won't reveal too much unless you know the router addresses at the remote end, but it might help to identify if the problem is somewhere along the way. WSAEPROTONOSUPPORT (10043) Protocol not supported.

Other information varies between different errors. WinSock description: Same as Berkeley. Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. Winsock Error 10054 Fix WinSock description: No equivalent.

This documentation is archived and is not being maintained. A blocking operation was interrupted by a call to WSACancelBlockingCall. -------------------------------------------------------------------------------- WSAEACCES Error Number: 10013 Permission denied. This value was also named DNS_ERROR_INVALID_NSEC3_PARAMETERS DNS_ERROR_NOT_ENOUGH_SIGNING_KEY_DESCRIPTORS 9104 (0x2390) The zone does not have enough signing keys. The socket input parameter is not a valid socket handle (either it never was valid, it's a file handle (not a socket handle), or if it was a socket handle, it

if(url.find("http://") == 0) url.erase(0, 7); // Get the host name. Wsagetlasterror 0 Let the network system assign the default local IP address by referencing INADDR_ANY in the sin_addr field of a sockaddr_in structure input to bind(). User suggestions: Check that you have a name server(s) and/or host table configured. Networking activity on the local host has not been initiated.

  • The WinSock implementation was unable to allocate additional memory to accommodate the function request.
  • This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in
  • The error can occur when the local network system aborts a connection.

Socket Error 10054 Connection Reset By Peer

A request to send or receive data was disallowed because the socket is not connected. -------------------------------------------------------------------------------- WSATIMEOUT Error Number: 10060 SMTP timeout error. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. Socket Error Codes Linux Berkeley description: The system detected an invalid address in attempting to use an argument of a call. Socket Error 10049 Reload to refresh your session.

Thirteen errors have "" next to the list of WinSock functions that can produce them. http://itechnologysolutionsllc.com/socket-error/windows-tcp-ip-error-codes.php However, there's little distinction between WSAEALREADY and WSAEINVAL since a WinSock DLL cannot tell the difference between an asynchronous operation that has been cancelled and one that was never valid. one with no server application running. -------------------------------------------------------------------------------- WSAEHOSTDOWN Error Number: 10064 Host is down. Error Codes - errno, h_errno and WSAGetLastError In Winsock applications, error codes are retrieved using the WSAGetLastError function, the Windows Sockets substitute for the Windows GetLastError function. Socket Error 11004

User suggestions: see WSAECONNABORTED for details. Cannot translate a name. See also: WSAEINVAL WSAENOTCONN (10057) Socket is not connected. this page WSAEBADF (10009) Bad file descriptor.

A Windows Sockets implementation may have a limit on the number of applications that may use it simultaneously. -------------------------------------------------------------------------------- More Information: See UBQ000162: Non-UltraBac Specific Registry Key: TcpMaxDataRetransmissions Copyright UltraBac Windows Socket Error Windows 10 An address incompatible with the requested protocol was used. The "address" it refers to is the remote socket name (protocol, port and address).

Windows Sockets only allows a single blocking operation. -------------------------------------------------------------------------------- WSAEALREADY Error Number: 10037 Operation already in progress.

Berkeley description: An address incompatible with the requested protocol was used. Would it be inappropriate to use my workplace's postage machine to mail my tax returns? And should i deallocate memory with LocalFree(Error)? –Stefano Jan 8 '11 at 11:08 Because then you would be passing the address of pointer (which expects a type of pointer Socket Error 10061 Connection Refused Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent

C# Generics - How to avoid redundant method? If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address. See WSASYSNOTREADY for details. Get More Info A QoS error occurred due to lack of resources.

An operation was attempted on a nonblocking socket with an operation already in progress—that is, calling connect a second time on a nonblocking socket that is already connecting, or canceling an 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 The protocol family has not been configured into the system or no implementation for it exists. Ping a host on the same subnet as the host you were connected to (if you know one).

Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE on a connection that's already timed out. A socket already has a type (a protocol), and each sockaddr structure has an address family field to define its format. See WSAENETUNREACH.

The v1.1 specification also lists connect(), although it does not allocate a descriptor. Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections. You need to note both the programmatic and the run-time context in which these errors occur.

It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans"). WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable. Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). You must free the memory when it is no longer needed. –cpx Jan 8 '11 at 13:20 add a comment| up vote 1 down vote Hi you can use this code

The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error. WSAEISCONN (10056) Socket is already connected. The WSAGetLastError function is intended to provide a reliable way for a thread in a multithreaded process to obtain per-thread error information.

Each implementation may have a maximum number of socket handles available, either globally, per process or per thread. -------------------------------------------------------------------------------- WSAENOTSOCK Error Number: 10038 Socket operation on non-socket. This error apparently also takes the place of WSAEPFNOSUPPORT (which means "protocol family not supported"), since that error is not listed for socket() in the v1.1 WinSock specification. Zone signing will not be operational until this error is resolved. DNS_ERROR_KSP_DOES_NOT_SUPPORT_PROTECTION 9108 (0x2394) The specified key storage provider does not support DPAPI++ data protection.
