The lpOverlapped parameter must be valid for the duration of the overlapped operation. When the TransmitPackets() function completes, the socket handle can be passed to the AcceptEx() function. WSA_QOS_ESERVICETYPE 11016 QoS service type error. The completion routine follows the same rules as stipulated for Windows file I/O completion routines. have a peek at these guys
In the Application page, select Empty project for the Additional options:. A common error is WSAECO-NNABORTED, which occurs when the virtual circuit terminates because of a timeout failure or a protocol error. WSASend function The WSASend function sends data on a connected socket. Return value If no error occurs and the send operation has completed immediately, WSASend returns zero.
You must purchase the product, or else uninstall the software 736 You need a professional or distribution license to use this function Errors 1000-1999 (Licensing) Error Description 1001 Evaluation period has A socket operation encountered a dead host. The specified class was not found.
The password might have been too short or might have matched a previously used password 31710 Serial overrun errors were detected while communicating with the modem 31711 A configuration error on WSAEINPROGRESS - 10036 Operation now in progress. An application used a Windows Sockets function which directly maps to a Windows function. What Is A Socket Error The WSASend() function sets lpNumberOfBytesSent to the number of bytes written.
share|improve this answer answered Mar 8 '15 at 11:58 Filip Roséen - refp 39.6k1189154 Could the down-voters clarify what is wrong with this answer? Winsock Error Codes WSAEINVAL The socket has not been bound with bind or the socket is not created with the overlapped flag. WSAESHUTDOWN 10058 Cannot send after socket shutdown. Returning from this function allows invocation of another pending completion routine for this socket.
If you are using I/O completion ports, be aware that the order of calls made to WSASend is also the order in which the buffers are populated. Wsabuf WSAEBADF 10009 File handle is not valid. The MSG_DONTROUTE flag tells the transport not to route the packets it sends. Click Project menu > Add New Item sub menu or select the project folder in the Solution Explorer > Select Add menu > Select New Item sub menu. 6.
The owners of this site are compensated by relationships with the recommended software products. < Client APIs & TCP States | Winsock2 Main | TCP Client-server Examples > An A Windows Sockets service provider can choose to ignore this flag. Wsasend Vs Send If lpCompletionRoutine is not NULL, the hEvent parameter is ignored and can be used by the application to pass context information to the completion routine. Wsasendto If both lpOverlapped and lpCompletionRoutine are NULL, the socket in this function will be treated as a non-overlapped socket.
Put the project and solution name. More about the author Data is copied from the buffer(s) into the transport's buffer. The protocol entry for each protocol contains a flag indicating whether it supports this feature. Invalid SOAP data received 22128 Failed to retrieve performance counter. Wsarecv
The third parameter indicates the number of WSABUF structures being passed. This data was ignored 31723 The phone number, including prefix and suffix, is too long 31724 The IPX protocol cannot dial out on the modem (or other connecting device) because this Trick or Treat polyglot Should the sole user of a *nix system have two accounts? check my blog WSA_OPERATION_ABORTED The overlapped operation has been canceled due to the closure of the socket, the execution of the "SIO_FLUSH" command in WSAIoctl, or the thread that initiated the overlapped request exited
Elaboration I'm actually not sure how to answer this question without yelling out "No, read the documentation!". Wsareceive Calling closesocket() releases the socket descriptor and any further calls using the socket fail with WSAENOTSOCK. In reality, it can be a buffer with any raw data in it, whether it's binary or string data doesn't matter.
WSAEHOSTUNREACH 10065 No route to host. Connect to the server with 'accept host key' enabled to accept and store the host key. 22496 Host key changed. 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. Wsagetlasterror The support for the specified socket type does not exist in this address family.
That is, the semantics of this function are determined by the socket options and the dwFlags parameter. Errors are listed in numerical order with the error macro name. WSAESOCKTNOSUPPORT 10044 Socket type not supported. news For a UDP datagram socket, this error would indicate that a previous send operation resulted in an ICMP "Port Unreachable" message.
This normally results from an attempt to bind to an address that is not valid for the local computer. Pending overlapped operations are also canceled. This permits time-sensitive data transmissions to occur entirely within a preemptive context. Two specific ways of implementing urgent data currently exist for TCP.
An invalid QoS filter type was used. You might wonder why you would want to send more than one buffer at a time. 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. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server).
Note that not all connection-oriented protocols support graceful closure, which is what the shutdown() API performs. 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.
