Winsock Error Code 10040

Berkeley description: A connect request was made on an already connected socket; or, a sendto() or sendmsg() request on a connected socket specified a destination when already connected. However, because a BSD socket is equivalent to a file handle, some Windows Sockets platforms provide some file handle and socket equivalency. WSAEPFNOSUPPORT 10046 Protocol family not supported. A completion indication will be given at a later time when the operation has been completed.WSA_IO_INCOMPLETE (OS dependent)Overlapped I/O event object not in signaled state.The program has tried to determine the his comment is here

User suggestions: Check that you have a name server(s) and/or host table configured. WSA_QOS_POLICY_FAILURE 11011 QoS policy failure. 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. WSAEMSGSIZE (10040) Message too long.

Covered by US Patent. The occurrence of an unlisted error can provide extra detail. This is not a temporary error.

  1. For example, this error is returned if sendto is called with the remote address of ADDR_ANY.
  2. 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
  3. In this case, the 2nd application will fail with WSAEADDRINUSE.
  4. WSA_QOS_RESERVED_PETYPE 11031 Reserved policy QoS element type.
  5. A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied.
  6. WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other
  7. The requested address is not valid in its context.

Why can't the second fundamental theorem of calculus be proved in just two lines? Some WinSock implementation use these errors inappropriately, but they have a particular meaning. This is a generic error code, returned under various conditions. Check that no old Windows Sockets DLL files are being accessed.WSAEDISCON (10094)Graceful shutdown in progress.Returned by recv, WSARecv to indicate the remote party has initiated a graceful shutdown sequence.WSA_OPERATION_ABORTED (OS dependent)Overlapped

Request refused: name server refuses to satisfy your query for policy reasons. Then i divide the total file size into chunks of 8192 bytes and send each chunk thru the "sendingSocket" (In this case i get 2 chunks: 1 whole chunk of 8192 Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function. By calling shutdown() you do a partial close of a socket, which means you have discontinued sending.

Too many links were encountered in translating a pathname. User suggestions: Chances are the network subsystem is misconfigured or inactive. Programming Languages-Other C++ Introduction to C++: Functions - The Return Statement Video by: Ian The viewer will learn how to use the return statement in functions in C++. WSA_QOS_EFLOWSPEC 11017 QoS flowspec error.

Among other things, that is exactly what we've done here. browse this site Posted on 2003-05-03 Programming Languages-Other Programming 1 Verified Solution 3 Comments 5,200 Views Last Modified: 2013-11-13 Background Info: I am trying to write a program on Windows(WinSock) that creates 2 SOCK_DGRAMs Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router. 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.

WinSock functions: WSAENOTSOCK (10038) Socket operation on non-socket. this content WSAENOBUFS 10055 No buffer space available. It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request.

the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! weblink Windows Sockets only allows a single blocking operation to be outstanding per task (or thread), and if any other function call is made (whether or not it references that or any

WinSock description: Same as Berkeley. Additional functions: With a datagram socket: send() or sendto(), or FD_READ. Berkeley description: A socket operation was attempted to an unreachable host.

WSAEREMOTE 10071 Item is remote.

WSAHOST_NOT_FOUND 11001 Host not found. SO_ACCEPTCONN, SO_ERROR, SO_TYPE: are read-only options, so they work with getsockopt(), but not with setsockopt() Developer suggestions: Check the parameters. This may be because the database files (e.g. You should simply ignore this error when it occurs.

WSAEPROCLIM 10067 Too many processes. WSAEADDRINUSE 10048 Address already in use. When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. http://pdctoday.com/winsock-error/winsock-error-code-40006.php The service provider procedure call table is invalid.

Detailed description: recv() and recvfrom(): if the datagram you read is larger than the buffer you supplied, then WinSock truncates the datagram (i.e. To recover the orphaned sockets, you can try closing the application and restarting it to recover the open sockets; you may have to end all WinSock applications (to force an unload A call to the WSALookupServiceEnd function was made while this call was still processing. See also: WSAENETUNREACH WSAEINPROGRESS (10036) Operation now in progress.

Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH. The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them. User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O. This error may also be returned for protocol and service queries, and means that the specified name could not be found in the relevant database.

Not the answer you're looking for? please advise -------- start code //##################################################################### int recv() { // start receiving data from sendbuffer to bufrecv int recv,totalrecv =0; SOCKADDR_IN from; /* Sender's address. */ WSA_QOS_ADMISSION_FAILURE 11010 QoS admission error. WSAEBADF 10009 Bad file number.

all other functions: retry the operation again later since it cannot be satisfied at this time. An application attempts to use an event object, but the specified handle is not valid. Developer suggestions: If you don't detect it beforehand (e.g.
