Socket Error 13 Description


WinSock description: No equivalent. For possible values, see table below. Check the destination address you are using. The error occurs with the socket() function, which takes the socket type (protocol) and address family as input parameters.

When it occurs, it could indicate a serious failure of your network system (i.e. TCP recv() or UDP recvfrom(): receive a message from a socket char *pcIpAddress; unsigned short shPort; ... ... WinSock description: Same as Berkeley. In this case, the WSAEBADF error might mean the same as a WSAENOTSOCK error.

Socket.error Errno 13 Permission Denied Port 80

The TCP_KEEPIDLE option can be used to affect this value for a given socket, and specifies the number of seconds of idle time between keepalive probes. Berkeley description: Only one usage of each address is normally permitted. This enum was introduced or modified in Qt 5.0.

An invalid value was given for one of the arguments to a function. When the connection has been established, it enters ConnectedState and emits connected(). See also state(). [virtual] qintptr QAbstractSocket::socketDescriptor() const Returns the native socket descriptor of the QAbstractSocket object if this is available; otherwise returns -1. Socket Error 10054 bytesAvailable() then returns the number of bytes that are available for reading.

  3. This book is a must for any serious UNIX/Linux programmer.
  4. int backlog: Set maximum length of the queue of pending connections for the listening socket.
  5. See also state() and errorString(). [signal] void QAbstractSocket::error(QAbstractSocket::SocketError socketError) This signal is emitted after an error occurred.
  6. The error can also occur in an attempt to rename a file or directory or to remove an existing directory.

QAbstractSocket::SslInternalError20The SSL library being used reported an internal error. Detailed description (from RFC 1035, "Domain Names", by P.Mockapetris): Format error: name server was unable to interpret the query. Socket.error Errno 13 Permission Denied Port 80 User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? Socket Error Codes Linux WinSock description: Partly the same as Berkeley.

For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open The function returns true if the bytesWritten() signal is emitted; otherwise it returns false (if an error occurred or the operation timed out). The close() function call was made a little more specific for the Win32 platform. IPPROTO_IPTCP_KEEPIDLEint7200When the SO_KEEPALIVE option is enabled, TCP probes a connection that has been idle for some amount of time. What Is A Socket Error

We show an example: int numRead = 0, numReadTotal = 0; char buffer[50]; forever { numRead =, 50); // do whatever with array numReadTotal += numRead; if (numRead == 0 WinSock description: Same as Berkeley. This error occurs if the sin_addr is INADDR_ANY (i.e. check over here Developer suggestions: for protocols and services consider using a hard-coded value for the protocol number or service port number in case your resolution attempt fails, and you can have your cake

Python Socket Error Errno 98 Address Already In Use Because of this, calling this function on QUdpSocket has no effect. struct timeval *timeout: This structure holds the upper bound on the amount of time elapsed before select returns.

Berkeley description: Too many open files.

This feature is commonly used by proxy connections for virtual connection settings. Richard Stevens, Bill Fenner, Andrew M. send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already Socket Error 10049 A blocking socket doesn't require an event loop and typically leads to simpler code.

This is not necessarily true for a TCP stream. you tried to connect to the wrong destination host address the server application isn't running on the destination host the server application isn't listening on the right port. a TCP reset received from remote host). this content All processes that share the port must specify this option.0 = disables, 1 = enables SOL_SOCKETSO_ERRORint(bool)0When an error occurs on a socket, set error variable so_error and notify process0 = disables,

See also pauseMode() and resume(). [protected] void QAbstractSocket::setPeerAddress(const QHostAddress &address) Sets the address of the remote side of the connection to address. See also proxy(), QNetworkProxy, and QNetworkProxyFactory::queryProxy(). [virtual] void QAbstractSocket::setReadBufferSize(qint64 size) Sets the size of QAbstractSocket's internal read buffer to be size bytes.

TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent. struct sockaddr *addr: Pointer to a sockaddr structure. The v1.1 specification also lists connect(), although it does not allocate a descriptor. If we assumed OP should know everything, there'd be no SO. –utdemir Jun 2 '14 at 18:47 I would like to know on which port my python is writing

For TCP sockets, this function may be used to specify which interface to use for an outgoing connection, which is useful in case of multiple network interfaces. Does a natural 20 on an animal handling check do anything special? WinSock description: No equivalent. Microsoft C description: Bad file number.

User suggestions: see WSAECONNABORTED for details. Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. See "Tips and Best Practices" below. The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock.

WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available").
