Windows Socket Error 10042

Contents

WinSock description: No equivalent. This is equivalent (in some sense) to either trying to use a resource/memory after you free it, or simply referencing an uninitialized pointer. Since the buffering requirements for sending are less than for receiving datagrams, it's conceivable that you can send a datagram larger than you can receive. The error occurs with the socket() function, which takes the socket type (protocol) and address family as input parameters. http://jactionscripters.com/socket-error/winsock-error-10042.php

WinSock description: No equivalent. On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. you're trying to share a socket between tasks). For example, if a call to WaitForMultipleObjects fails or one of the registry functions fails trying to manipulate theprotocol/namespace catalogs.WSASYSNOTREADY (10091)Network subsystem is unavailable.This error is returned by WSAStartup if the https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

WSAEPROTONOSUPPORT (10043) Protocol not supported. These are response codes which the SMTP protocol has defined to communicate various states during client-server communication. Berkeley description: An attempt was made to access an open file (on an NFS filesystem) which is now unavailable as referenced by the file descriptor. Socket Error 11004 The WinSock description for this error is "the specified socket type is not supported in this address family," which qualifies the error condition a bit more than the Berkeley explanation does.

AF_INET for Internet Protocols) and a generic protocol type (i.e. Tried an unreachable network socket operation . 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 Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value

If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. Windows Socket Error Windows 10 Protocol stack is not configured or no implementation for it exists in the system. This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.

Socket Error 10054 This error is also possible on a datagram socket; for instance, this error could result if your application sends a UDP datagram to a host, which rejects it by responding with Socket Error 10054 Connection Reset By Peer Specifically, these error-less functions are the byte order functions ( htonl(), htons(), ntohl(), and ntohs()), the address manipulation functions (inet_addr(), and inet_ntoa), WSAGetLastError() and WSAIsBlocking().

Client programs usually need not call bind at all - connect will choose an unused port automatically.WSAEADDRNOTAVAIL (10049)Cannot assign requested address.The requested address is not valid in its context. weblink PublicSharedSubMain() 'Databufferforincomingdata. Are you using an optional level or socket option that may not be supported on all WinSock implementations? Group list elements using second list Why does Wolfram Alpha say the roots of a cubic involve square roots of negative numbers, when all three roots are real? Socket Error 10053

  1. The WSAAsyncSelect() FD_WRITE event is specifically designed to notify an application after a WSAEWOULDBLOCK error when buffer space is available again so send() or sendto() should succeed.
  2. before calling connect() or accept()).
  3. Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function.
  4. This normally results if the peer program on the remote host is suddenly stopped, the host is rebooted, or the remote host used a "hard close" (see setsockopt for more information
  5. Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a WinSock DLL to send a DNS "A" record query
  6. Thirteen errors have "" next to the list of WinSock functions that can produce them.
  7. 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.

  10. WinSock description: Same as Berkeley.

There are only a few possible causes for this error: you tried to connect to the wrong port. WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported. See also: WSAEAFNOSUPPORT WSAEPROCLIM (10067) Too many processes. navigate here If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP.

And how to fix it??? (I also wrote a client app to prove it with my server side app and it works good) I'm posting the entery code so you can Winsock Error 10054 Fix Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. Note: this error may also result if you are trying to send a multicast packet and the default gateway does not support multicast (check your interface configuration).

In getsockopt () or setsockopt () call , specify an unknown , illegal or unsupported option or level (level).

WSAEISCONN (10056) Socket is already connected. Do you understand this Error msg (ERROR Msg 512, Level 16, State 1, Line 33) error: unrecognized option `-feliminate-unused-debug-types' Error Locating Server/Instances Specified (VS to SqlSvr) Error connecting to SQLExpress 2005 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 Socket Error 10061 Connection Refused Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified?

closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. Developer suggestions: Always check the return value from a memory allocation to be sure it succeeded. If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet his comment is here It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans").
