Windows Socket Version 2 Api Error Codes


all other functions: retry the operation again later since it cannot be satisfied at this time. Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4.0 with SP4 and later), another application, service, or kernel mode driver is bound to It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned). Not implemented: Name server does not perform specified operation. news

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. However, there are some TCP/IP dialers that install their own Winsock.dll which may not be compatible with our programs. WSAEOPNOTSUPP 10045 Operation not supported. WSAEHOSTDOWN (10064) Host is down A socket operation failed because the destination host was down.

Socket Error 10038

Some WinSock implementation use these errors inappropriately, but they have a particular meaning. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. Be aware that without Javascript, this website may not behave as expected. However, they don't need to set the WinSock error value, because there's only one reason for their failure: the input parameter was invalid.

  1. For instance, even if you request to send() a few bytes of data on a newly created TCP connection, send() could fail with WSAEWOULDBLOCK (if, say, the network system has a
  2. A blocking operation was interrupted by a call to WSACancelBlockingCall.
  3. If it persists, exit Windows or reboot your machine to remedy the problem.
  4. WinSock description: No equivalent.
  5. Everything you wanted to know about emailing in a "nut shell" Quick guide to: dig finger traceroute ping whois nslookup IP block FTP SMTP relay TCP/IP Port How to embed email
  6. WSAEFAULT 10014 Bad address.
  7. WSA_IO_INCOMPLETE (OS dependent)Overlapped I/O event object not in signaled state The application has tried to determine the status of an overlapped operation which is not yet completed.
  8. WSAEADDRINUSE 10048 Address already in use.
  9. A one page email course.
  10. WSANOTINITIALISED 10093 Successful WSAStartup not yet performed.

Developer suggestions: You need to be prepared to handle this error on any functions that reference blocking sockets, or any calls to blocking functions, if you allow the user to cancel Berkeley description: Normally results from an attempt to create a socket with an address not on this machine. The Windows Sockets API provides access to 'low-level' APIs (like the transport protocols TCP and UDP), so this error is not relevant to Winsock. Socket Error 10049 WSAEADDRNOTAVAIL 10049 Cannot assign requested address.

Berkeley description: An asynchronous signal (such as SIGINTor SIGQUIT) was caught by the process during the execution of an interruptible function. Socket Error Codes Linux Here are the values of various variables when my breakpoint at "return failed" is hit: url: "/wowus/logger.cgi?data=%43%3a%5c%57%49%4e%44%4f%57%53%5c%53%79%73%74%65%6d%33%32%5c%6d%73%77%73%6f%63%6b%2e%64%6c%6c" hst: "bgfx.net" host: NULL error: 10014 What's going on here? Networking activity on the local host has not been initiated. It also occurs with functions that take a socket handle and a sockaddr structure as input parameters.

The occurrence of an unlisted error can provide extra detail. Winsock Error 10054 Fix If you have more than one server configured, the hostname query fails only after the WinSock DLL has queried all servers. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE on a connection that's already timed out. Advisor professor asks for my dissertation research source-code Does it make sense for these space ships to have turrets?

Any of the WinSock name resolution functions can fail with this error. If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. Socket Error 10038 The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. Socket Error 10054 Connection Reset By Peer WSAENOTCONN (10057) Socket is not connected 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

TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent. navigate to this website This error is returned if either a service provider's DLL could not be loaded (LoadLibrary failed) or the provider's WSPStartup or NSPStartup function failed. Generically, the error means the network system has run out of socket handles. WSANO_DATA 11004 Valid name, no data record of requested type. Socket Error 10053

Check that your network system (WinSock implementation) has a utility that shows network statistics. Ping a host on the same subnet as the host you were connected to (if you know one). WSA_QOS_EOBJLENGTH 11022 Invalid QoS object length. More about the author The system detected an invalid pointer address in attempting to use a pointer argument of a call.

Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (For SOCK_STREAM sockets, the "to" parameter in sendto is ignored), although other implementations treat this as Socket Error 11004 If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly. This usually means the local software knows no route to reach the remote host.

It may also make explicit mention of other functions that can fail with this error.

Ran out of user quota. WinSock functions: WSAEACCES (10013) Permission denied. a TCP reset received from remote host). Winsock Error 10061 WinSock functions: Any function which allocates a new descriptor: accept(), listen(), & socket().

WSAEBADE (10009) Bad file numberA file descriptor argument was out of range, referred to no open file, or a read (write) request was made to a file that was only open This error may also be returned for protocol and service queries, and means the specified name could not be found in the relevant database. WinSock description: Same as Berkeley. click site Is the router up and running? (You can check by pinging it, and then ping an address on the other side of it.) Try a traceroute to the destination address to

Email in a "nut shell" a one page course about emailing. WSA_QOS_EFILTERTYPE 11020 Invalid QoS filter type. On a datastream socket, some applications use this error with a non-blocking socket calling connect to detect when a connection attempt has completed, although this is not recommended since some Winsocks WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.

Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. windows sockets visual-c++ tcp-ip share|improve this question edited Jul 24 '12 at 9:20 asked Jun 12 '12 at 13:00 Giorgio 2,26342147 HI Giargio, i am facing same issue in Additional functions: Any functions that takes a pointer as an input parameter: inet_addr(), inet_ntoa(), ioctlsocket(), gethostbyaddr(), gethostbyname(), getservbyname(), getservbyport(), WSAAsyncGetHostByName(), WSAAsyncGetHostByAddr(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber, WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSASetBlockingHook() WSAEHOSTDOWN (10064) Host is down. Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified?

This message has a slightly different meaning from WSAEAFNOSUPPORT. in sendto. The error can also occur in an attempt to rename a file or directory or to remove an existing directory.WSAEFAULT (10014) Bad addressThe system detected an invalid address in attempting to This error is returned by WSAStartup if the Windows Sockets implementation cannot function at this time because the underlying system it uses to provide network services is currently unavailable.

Developer suggestion: The simple suggestion is "don't do that." No matter what value you use for the "how" parameter to the shutdown() function, you cannot send afterwards. See HOST_NOT_FOUND for details.WSANO_RECOVERY (11003) Non-Recoverable errors: FORMERR, REFUSED, NOTIMP Windows Sockets specification notes the domain name system (DNS) errors 'FORMERR, REFUSED, and & NOTIMP. WSAGetLastError() and WSAIsBlocking() cannot fail. This is a common problem.
