Windows Sockets Error Codes


However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket. LRS_SOCKET_DOESNT_EXIST 9002 An invalid socket descriptor was transferred to the function. Too many open sockets. You signed out in another tab or window. this contact form

WinSock description: Same as Berkeley. It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. The fourth part of the Windows Sockets error code of getXbyY () and WSAAsyncGetXByY () function returns , the equivalent of Berkeley software error returned by the variable h_errno (in fact You could use this to verify that you're receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect.

Socket Error 10054 Connection Reset By Peer

A retry at some time later may be successful. Additionally, the following more significant changes were incorporated into version 1.1: Inclusion of the gethostname() routine to simplify retrieval of the host's name and address. The "version 1.0 debate" hosted by Microsoft in Seattle allowed many of the members of the working group to hash out final details for 1.0 vis-a-vis.

  1. WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error.
  2. Clearly, this oversight was not intentional.
  3. A socket operation was attempted to an unreachable network.
  4. WSAHOST_NOT_FOUND 11001 Host not found WSATRY_AGAIN 11002 Try again WSANO_RECOVERY 11003 Non-recoverable error WSANO_DATA 11004 No data record available Send documentation feedback to HP Close We welcome your comments!

An incorrect number of QoS FILTERSPECs were specified in the FLOWDESCRIPTOR. via socket() TCP_NODELAY BOOL Disables the Nagle Implementation algorithm for send dependant. This allows users to choose between receiving the urgent data in order and receiving it out of sequence without having to buffer all the intervening data. Winsock Error 10054 Fix Joy, Phil Lapsley, Steve Miller, and Chris Torek.

Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. Socket Error Codes Linux This means another type of request to the name server will result in an answer. If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. Version 1.1 contains several clarifications and minor fixes to version 1.0.

WSA_IO_INCOMPLETE 996 Overlapped I/O event object not in signaled state. Socket Error 11004 Developers should consider handling the referenced errors similarly. The Windows header file windows.h is also needed, but winsock.h will include it if necessary. 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.

Socket Error Codes Linux

In general , Windows Sockets application should be interpreted as an error indication WSAHOST_NOT_FOUND and WSANO_DATA keyword ( name, address, etc. ) do not find it , and the error WSATRY_AGAIN https://gist.github.com/gabrielfalcao/4216897 Some network implementations and/or configurations perform network based operations to resolve such requests. Socket Error 10054 Connection Reset By Peer Meetings of interested parties occur on an irregular basis. Socket Error 10053 Otherwise, a value of SOCKET_ERROR is returned, and a specific error code may be retrieved by calling WSAGetLastError().

The communication seems to work for a while, then it stops working. weblink A datagram socket supports bi-directional flow of data which is not promised to be sequenced, reliable, or unduplicated. coalescing. If an application uses private interfaces of a particular vendor's Windows Sockets DLL, it is recommended that the DLL not be statically linked with the application but rather dynamically loaded with Socket Error 10049

Note that this error is returned by the operating system, so the error number may change in future releases of Windows. WinSock description: No equivalent. Berkeley Sockets error codes are defined in order to ensure the portability of the original software . navigate here List of contributors: Martin Hall (Chairman) JSB Corporation [email protected] Mark Towfiq (Coordinator) Microdyne Corporation [email protected] Geoff Arnold (Editor 1.0) Sun Microsystems [email protected] David Treadwell (Editor 1.1) Microsoft Corporation [email protected] Henry Sanders

WSAEADDRINUSE The specified address is already in use. (See the SO_REUSEADDR socket option under setsockopt().) WSAEFAULT The namelen argument is too small (less than the size of a struct sockaddr). Windows Socket Error Windows 10 Byte Ordering The Intel byte ordering is like that of the DEC VAX, and therefore differs from the Internet and 68000-type processor byte ordering. WinSock description: No equivalent.

The file's permission setting does not allow the specified access.

Berkeley description: A message sent on a socket was larger than the internal message buffer or some other network limit. If an application desires to bind to an arbitrary port outside of the range 1024 to 5000, such as the case of rsh which must bind to any reserved port, code Reload to refresh your session. Socket Error 10061 Connection Refused WinSock description: Same as Berkeley.

See also: These point to other errors that are similar. socket data type and error values select() and FD_* Error codes -- errno, h_errno & WSAGetLastError() Pointers Renamed functions Blocking routines & EINPROGRESS Maximum number of sockets supported Include files Return This can help you (or your support staff) to zero-in on what's wrong when your application runs into a problem. his comment is here A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call.

This implies an asymmetry in establishing communication between the client and server. This could happen with a call to another function later, including connect, listen, WSAConnect, or WSAJoinLeaf. WSAEINVALIDPROCTABLE 10104 Procedure call table is invalid. If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address.

An application used a Windows Sockets function that directly maps to a Windows function. This is a common problem. Members Members Quick Links Registered Members Current Visitors Recent Activity Help Help Quick Links Smilies BB Codes Trophies Cookie Usage Contact Us Home Top RSS Copyright © 2013 YooSecurity.com All Rights The first solution we tried (actually, it is rather a workaround) was resending the message when the error occurs.

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 Client applications usually need not call bind at all—connect chooses an unused port automatically. However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT. Berkeley description: A connection was forcibly closed by a peer.

This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. Not the answer you're looking for? What does the SO_LINGER option mean? In some instances, it also refers to the current state of the socket—for instance, calling accept on a socket that is not listening.

the communication can be both within the same host or between different hosts).
