I puzzled over this again and again. I would just use blocking mode, unless you know you need non-blocking, in which case you should certainly learn how to use select(). –EJP Jan 27 '13 at 23:19 add a The main source of these performance decreases are startup clutter, registry errors, RAM decline, fragmented files, unnecessary or redundant program installations, and more. WSAEINPROGRESS 10036 Operation now in progress. weblink

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 The Fix complete. *File size: 8.5MB Download time: <120 Secs When you have Wsaewouldblock Windows7 error then we strongly recommend that you run an error message scan. A blocking operation was interrupted by a call to WSACancelBlockingCall. An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.

WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. Berkeley description: The protocol family has not been configured into the system or no implementation for it exists. Wsaewouldblock Windows7 error codes are often brought on in one way or another by faulty files_new in the Microsoft Windows OS.

WSAENOTEMPTY 10066 Directory not empty. WinSock functions: connect(), FD_CONNECT Additional functions: Any function that does I/O on the network could generate this error, and the WSAAsyncSelect() events FD_OOB, FD_READ, FD_WRITE. Berkeley description: A connection abort was caused internal to your host machine. Socket Error 10038 WSAStartup may fail with this error if the limit has been reached.

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. Socket Error 10054 The system detected an invalid pointer address in attempting to use a pointer argument of a call. You could also try to resolve another hostname you know should work, to check that the name resolution server application is running. You need to call htons() to translate a constant value to network byte order before assigning it to the sin_port field in the sockaddr structure.

SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. Socket Error 10054 Connection Reset By Peer The v1.1 WinSock specification only ascribes thirty-three of the fifty errors to any of the WinSock functions in the v1.1 for Windows Sockets specification. When you remove programs from your PC, they don't always take out every single file, and some can be left there to interfere with your PCs functions. WSAEREFUSED 10112 Database query was refused.

  1. For example, if a call to WaitForMultipleEvents fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs.
  2. At least one QoS send path has arrived.
  3. WSAENETDOWN 10050 Network is down.
  4. 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
  5. WSA_E_CANCELLED 10111 Call was canceled.
  6. Resolution The speed of your PC can improve dramatically when you address all the problems just mentioned.
  7. WSAENAMETOOLONG 10063 Name too long.
  8. WinSock functions: WSAENETDOWN (10050) Network is down.
  9. WinSock description: No equivalent.
  10. So it would SEEM that since 10035 WSAEWOULDBLOCK is a non-fatal error, you should IGNORE IT TRY AND USE THE SOCKET ANYWAY.

Socket Error 10054

WinSock description: Similar to Berkeley & Microsoft C, the generic meaning is that an application passed invalid input parameter in a function call. WSA_QOS_EFLOWDESC 11026 Invalid QoS flow descriptor. Wsaewouldblock Sap Thirteen errors have "" next to the list of WinSock functions that can produce them. What Is A Socket Error Berkeley description: A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.) WinSock

WSAEHOSTUNREACH 10065 No route to host. have a peek at these guys An unknown or conflicting QoS style was encountered. Copyright 2000-2011 Chilkat Software, Inc. WSAEADDRINUSE 10048 Address already in use. Socket Error 10053

This usually results from trying to connect to a service that is inactive on the foreign host. Travel within Europe with a single entry visa How are brakes cooled on heavy aircraft? Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address. check over here When bind is called with a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until the specific address is committed.

if ( connect( g.s, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) { int err = WSAGetLastError(); printf( "Failed to connect: Error code: %d.\n", err ); WSACleanup(); return; } But what would happen Socket Error 10049 This means another type of request to the name server will result in an answer. In some instances, it also refers to the current state of the socket input parameter.

Developers should consider handling the referenced errors similarly.

The ICMP message means that a router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down). WSA_QOS_EFILTERSTYLE 11019 Invalid QoS filter style. while ( connect( g.s, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) { int err = WSAGetLastError(); printf( "Failed to connect: Error code: %d.\n", err ); printf( errCodes[ err ] ); //WSACleanup(); //return; Wsagetlasterror 0 TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data

Berkeley description: The host you were connected to crashed and rebooted. WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a Ran out of disk quota. this content Jan 27 '13 at 10:21 did you mean send() instead of socket()? (with proper parameters) –Davide Berra Jan 27 '13 at 15:50 Why are you using non-blocking

A socket already has a type (a protocol), and each sockaddr structure has an address family field to define its format. Berkeley description: A write to an ordinary file, the creation of a directory or symbolic link, or the creation of a directory entry failed because the user's quota of disk blocks TCP/IP scenario: In BSD-compatible implementations, the local network system generates this error if there isn't a default route configured. User suggestions: see WSAHOST_NOT_FOUND for details.

The protocol family has not been configured into the system or no implementation for it exists. Berkeley description: An operation that takes a long time to complete (such as a connect()) was attempted on a non-blocking socket. (see ioctl()). WinSock functions: recv(), recvfrom(), sendto(), FD_CLOSE Additional functions: send() can also fail with WSAECONNABORTED. WinSock functions: getpeername(), recv(), recvfrom(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAENOTEMPTY (10066) Directory not empty.

Review by : Marie Poole "My computer is consistently running smoother with less startup problems and faster connections than before. WSAEINVAL (10022) Invalid argument. If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address. WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported.

WSA_QOS_POLICY_FAILURE 11011 QoS policy failure. Some error codes defined in the Winsock2.h header file are not returned from any function. The file handle supplied is not valid. However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error.
