Windows Sockets Version 2 Api Error Codes


Two types of sockets currently are available to a user. When the program binds the socket it return the WSAError 10049. This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. WinSock functions: See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAEHOSTUNREACH (10065) No route to host. this contact form

However, a Windows Sockets DLL is allowed and encouraged to supply raw socket support. WSAEISCONN 10056 Socket is already connected. Another mechanism is for the intermediate DLL to build a table of task handles, which are obtained from the GetCurrentTask() Windows API, and at each entry point into the intermediate DLL What are the disadvantages of a delta wing biplane design?

Socket Error 10054

Mark Towfiq ([email protected]) Table of Contents Authors and Copyright Acknowledgments Introduction What is Windows Sockets Berkeley Sockets Microsoft Windows and Windows-specific extensions The Status of this Specification Revision History Windows Sockets A socket operation was attempted to an unreachable host. Check that no old Windows Sockets DLL files are being accessed. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.

  • It may also make explicit mention of other functions that can fail with this error.
  • the urgent data is delivered in sequence with the normal data), the system normally extracts the data from the normal data stream and stores it separately.
  • sendto()* Send data to either a connected or unconnected socket.
  • A problem was encountered with some part of the filterspec or the provider-specific buffer in general.

An example of a symmetric protocol is the TELNET protocol used in the Internet for remote terminal emulation. WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object. A reserved policy element was found in the QoS provider-specific buffer. Winsock Error 10054 Fix User suggestions: see WSAHOST_NOT_FOUND for details.

Check that no old Windows Sockets DLL files are being accessed. Application writers are cautioned that they should use the standard conversion functions provided as part of the Windows Sockets API rather than writing their own conversion code, since future implementations of No such service is known. https://msdn.microsoft.com/en-us/library/windows/desktop/cc507522(v=vs.85).aspx By calling shutdown() you do a partial close of a socket, which means you have discontinued sending.

It's also possible that the local services file has an incorrect port number (although it's unlikely). Socket Error 11004 It is normal for WSAEWOULDBLOCK to be reported as the result from callingconnecton a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established. An incorrect number of flow descriptors was specified in the QoS structure. When applied to a blocking socket, these operations are referred to as blocking operations.

Socket Error Codes Linux

Users should check: · That the appropriate Windows Sockets DLL file is in the current path. · That they are not trying to use more than one Windows Sockets implementation simultaneously. http://stackoverflow.com/questions/14366048/bind-fails-with-windows-socket-error-10049 WSA_QOS_BAD_OBJECT 11013 QoS bad object. Socket Error 10054 a buffer, or a global variable) as an argument, it is the responsibility of the application to ensure that the object is available to the Windows Sockets implementation throughout the operation. Socket Error 10054 Connection Reset By Peer These conditions are more likely to be indicated by the error WSAETIMEDOUT.

Basically, you want to identify where the problem occurred. http://jactionscripters.com/socket-error/windows-socket-version-2-api-error-codes.php Berkeley description: A socket operation failed because the destination host was down. Developer suggestions: Things an application developer can do to avoid the error. WSAEHOSTDOWN 10064 Host is down. Socket Error 10053

The name is not an official host name or alias, or it cannot be found in the database(s) being queried. bind() Assign a local name to an unnamed socket. WinSock functions: Additional functions: For Berkeley compatibility, the socket() function should fail with this error if an unsupported address family is requested. navigate here WSANO_DATA 11004 Valid name, no data record of requested type.

SO_REUSEADDR BOOL The address to which FALSE this socket is bound can be used by others. Windows Socket Error Windows 10 See WSASYSNOTREADY for details. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for.

The protocol family has not been configured into the system or no implementation for it exists.

These errors might be reported on any function that does network I/O (e.g. Portions of the Windows Sockets specification are derived from material which is Copyright (c) 1982-1986 by the Regents of the University of California. For example, if a call toWaitForMultipleEventsfails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs. Winsock Error 10061 WinSock functions: Additional functions: If a WinSock implementation has an upper limit to the number of simultaneous tasks it can handle, an application's initial call to WSAStartup() could fail with

In this case, the 2nd application will fail with WSAEADDRINUSE. Certain error codes returned by certain Windows Sockets routines fall into the standard range of error codes as defined by Microsoft C. There are, obviously, some drawbacks. his comment is here The sockaddr structure is defined as follows: struct sockaddr { u_short sa_family; char sa_data[14]; }; namelen The length of the name.

bind(), getsockopt(), getpeername()) can be completed immediately. Functionless Errors There are a total of fifty unique WinSock error values. Downloads and tools Windows 10 dev tools Visual Studio Windows SDK Windows Store badges Essentials API reference (Windows apps) API reference (desktop apps) Code samples How-to guides (Windows apps) Learning resources 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.

Updates in Windows 8[edit] Windows 8 includes the "RIO" (Registered IO) extensions for Winsock.[1] These extensions are designed to reduce the overhead of the user to kernel mode transition for the However a Windows Sockets implementation must not return any value which is not enumerated in the table of legal Windows Sockets errors given in Error Codes. For Winsock functions that return a pointer, a return value of NULL indicates an error and a specific error number can be retrieved by calling the WSAGetLastError function. WinSock description: No equivalent.

Database Files The getXbyY() and WSAAsyncGetXByY() classes of routines are provided for retrieving network specific information. WinSock description: Same as Berkeley for host resolution. Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol When the communication does not work, we get an error (apparently while a process was trying to send data).

Specifications[edit] Version 1.0 (June 1992) defined the basic operation of Winsock.
