Winsock Returned Error Code 10050


WSAENOPROTOOPT 10042 Protocol not available/bad protocol option. WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent. WinSock description: Same as Berkeley. It is also possible that WinSock might return this error after an application calls connect() a second time on a non-blocking socket while the connection is pending (i.e. news

For WinSock, this error is equivalent to Berkeley's EHOSTUNREACH error, the catch-all error for unreachable hosts. "You can't get there from here." TCP/IP scenario: The local network system could generate this SO_DEBUG, SO_DONTROUTE, SO_RCVBUF, SO_SNDBUF, TCP_NODELAY: optional socket options. The v1.1 WinSock specification doesn't list any errors for these functions. Not the answer you're looking for? https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

What Is A Socket Error

Can you ping that hostname? string hst = url.substr(0, url.find('/', 0)); url.erase(0, url.find("/", 0)); // Connect to the host. This is not a temporary error.

  • WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: Any function that does network I/O: recv(), recvfrom(), send(), FD_READ, FD_WRITE See also: WSAEHOSTUNREACH WSAENOBUFS (10055) No buffer space available.
  • It may also indicate you are not closing the applications properly.
  • Detailed descriptions (relevant to socket states): accept(): listen() was not invoked prior to accept() bind(): socket already bound to an address getsockname(): socket not bound with bind() listen(): socket not bound
  • When we are finished, we should be able to troubleshoot our applications so we can pinpoint where a problem may exist with greater efficiency.
  • Now we examine error handling in greater detail.
  • Not implemented: name server does not perform specified operation.
  • This has no network-relevant analog (although the "inode" reference could refer to a network file system entry).
  • WinSock functions: recv(), recvfrom(), send(), sendto() WSAENAMETOOLONG (10063) File name too long.
  • They signal unusual error conditions for which there's no WinSock error equivalent.

Some of the types of things you will find under some errors are: Microsoft C description: the first few WinSock errors are carry-overs from the standard 'C' runtime library. You could also try to resolve another hostname you know should work, to check that the name resolution server application is running. Socket Error 11004 Berkeley description: The protocol has not been configured into the system, or no implementation for it exists.

How would you know what went wrong? Socket Error Codes Linux This message indicates that the key (name, address, and so on) was not found. Developers should consider handling the referenced errors similarly. http://support.dameware.com/kb/article.aspx?ID=300058 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.

However, because a BSD socket is equivalent to a file handle, some Windows Sockets platforms provide some file handle and socket equivalency. Winsock Error 10054 Fix If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly. According to Microsoft: "This behavior may occur when you use an Internet security (personal firewall) program to protect your computer. The "address" it refers to is the remote socket name (protocol, port and address).

However, it also occurs when an application passes an invalid pointer value. http://www.sockets.com/err_lst1.htm Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP. What Is A Socket Error Developer suggestions: to make your application more portable: with datagram sockets don't use connect() and sendto() on the same datagram socket in an application, and always "disconnect" before calling connect() more Winsock Error 10053 This is what occurs in Berkeley Sockets.

If you have more than one server configured, the hostname query fails only after the WinSock DLL has queried all servers. http://jactionscripters.com/socket-error/winsock-returned-error-code-10038.php If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address. Socket Error 10054 Connection Reset By Peer

Alternately, you could call getprotobyname() or WSAAsyncGetProtoByName() to get the appropriate protocol value from the network system. User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O. c++ winsock share|improve this question edited Dec 25 '15 at 21:31 Bo Persson 59.3k1276142 asked May 10 '13 at 7:20 UnTraDe 1,35831634 Are you possibly calling WSACleanup somewhere, like http://jactionscripters.com/socket-error/winsock-returned-error-code-10093.php The service is unavailable. {{offlineMessage}} Store Store home Devices Microsoft Surface PCs & tablets Xbox Virtual reality Accessories Windows phone Software Office Windows Additional software Apps All apps Windows apps Windows

Socket Error 10061 Connection Refused Developer suggestions: Things an application developer can do to avoid the error. Microsoft C description: Too many open files.

You should now begining to see a pattern forming with our error checking. WSAESTALE 10070 Stale NFS file handle WSAEREMOTE 10071 Too many levels of remote in path. Detailed description: send() & sendto(): the requested address is a broadcast address, but the appropriate flag was not set (i.e. Socket Error 11001 Clearly, this oversight was not intentional.

Calls to WSAStartup() and WSACleanup() must be balanced at all times. Achieve same random number sequence on different OS with same seed How do I amplify a 0-100mV signal to an ADC with a range from 0 to a specific reference voltage? See also: These point to other errors that are similar. http://jactionscripters.com/socket-error/winsock-returned-error-code-10048.php We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause.

WSAEMFILE 10024 Too many open files/sockets. WSAEINVAL (10022) Invalid argument. This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. This means, the version we are trying to use doesn't exist.

Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent you didn't call setsockopt(SO_BROADCAST)). The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below). We can test this by inducing an error into our code.

WinSock functions: socket() See also: WSAEPROTOTYPE, WSAEPROTONOSUPPORT WSAESTALE (10070) Stale NFS file handle. Check your subnet mask. User suggestions: Check your WinSock, protocol stack, network driver and network interface card configuration. This can help you (or your support staff) to zero-in on what's wrong when your application runs into a problem.
