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. Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread. In some instances, it also refers to the current state of the socket-for instance, calling accept on a socket that is not listening. Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt function). For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr). This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. The system detected an invalid pointer address in attempting to use a pointer argument of a call. Such exclusive access is a new feature of Windows NT 4.0 with SP4 and later, and is implemented by using the SO_EXCLUSIVEADDRUSE option.īad address. Elinks error reading from socket driver#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 the same address with exclusive access. An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST). An attempt was made to access a socket in a way forbidden by its access permissions. A blocking operation was interrupted by a call to WSACancelBlockingCall.įile handle is not valid. A completion indication will be given later when the operation has been completed. The application has initiated an overlapped operation that cannot be completed immediately. Overlapped operations will complete later. Elinks error reading from socket code#Applications that use WSAGetOverlappedResult (with the fWait flag set to FALSE) in a polling mode to determine when an overlapped operation has completed, get this error code until the operation is complete. ![]() The application has tried to determine the status of an overlapped operation which is not yet completed. ![]() Overlapped I/O event object not in signaled state. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. Elinks error reading from socket windows#The Windows function is indicating a problem with one or more parameters. An application used a Windows Sockets function which directly maps to a Windows function. ![]() The Windows function is indicating a lack of required memory resources. An application used a Windows Sockets function that directly maps to a Windows function. An application attempts to use an event object, but the specified handle is not valid. Specified event object handle is invalid. Some error codes defined in the Winsock2.h header file are not returned from any function. Errors are listed in numerical order with the error macro name. The following list describes the possible error codes returned by the WSAGetLastError function. Elinks error reading from socket how to#The FormatMessage function can be used to obtain the message string for the returned error.įor information on how to handle error codes when porting socket applications to Winsock, see Error Codes - errno, h_errno and WSAGetLastError. These error codes and a short text description associated with an error code are defined in the Winerror.h header file. 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. The WSAGetLastError function returns the last error that occurred for the calling thread. For information, see the Handling Winsock Errors topic. Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns. ![]()
