Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). WinSock description: Partly the same as Berkeley. Berkeley description: Normally results from an attempt to create a socket with an address not on this machine. They signal unusual error conditions for which there's no WinSock error equivalent.
Note that the v1.1 WinSock specification does not explicitly state that this error occurs if the value you request is larger than the WSAData.iMaxUdpDg returned from WSAStartup(). WinSock description: Same as Berkeley. Developer suggestions: If you have a network analyzer available, you can quickly check if the destination port number and host address are what you expect. Resolution The speed of your PC can improve dramatically when you address all the problems just mentioned.
It may also indicate you are not closing the applications properly. Disclaimer: The views expressed on this blog are those of the author(s), and not those of the Microsoft Corporation. Developer suggestions: Handle this as a non-fatal error. Berkeley description: An asynchronous signal (such as SIGINTor SIGQUIT) was caught by the process during the execution of an interruptible function.
- WSAGetLastError() and WSAIsBlocking() cannot fail.
- It’s the normal error message format utilized by Microsoft Windows and other Microsoft Windows compatible applications and driver manufacturers.
- 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.
- See WSASYSNOTREADY for details.
- In some cases these errors are platform dependent.
- Any one of the preceeding actions can end up in the removal or data corruption of Windows system files.
- What causes Wsaenotempty error message?
- WinSock functions:
WSAENOTSOCK (10038) Socket operation on non-socket.
- Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions.
WinSock description: Same as Berkeley; the option is unknown or unsupported. Generically, the error means the network system has run out of socket handles. Request refused: name server refuses to satisfy your query for policy reasons. This software program has already proven its ability to locate and repair Windows errors.
Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. This particular code can be used by the supplier to identify the error made. This error apparently also takes the place of WSAEPFNOSUPPORT (which means "protocol family not supported"), since that error is not listed for socket() in the v1.1 WinSock specification. See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET WSAETOOMANYREFS (10059) Too many references; can't splice Berkeley description: too many references to some kernel-level object; the associated resource has run out.
Ping a host on the same subnet as the host you were connected to (if you know one). I hope you find it useful. Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH. 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
Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. It can delete junk files, decrease your startup time, restore lost memory, defragment your hard drive, remove spyware and malware, and lots more. TCP/IP scenario: description of the TCP/IP protocol suite network traffic (i.e. 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
Berkeley description: The attempted operation is not supported for the type of object referenced. WinSock description: Same as Berkeley. Berkeley description: A connection abort was caused internal to your host machine. WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available").
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. Do you have a router configured? 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 This error is relevant to connect(), but not to send() or sendto() as it is in Berkeley Sockets.
Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified? WinSock description: Partly the same as Berkeley. Beginner Computer User Fix (totally automatic): 1) Download and open the (Wsaenotempty) repair software application. 2) Install application and click on Scan button. 3) Press the Fix Errors button in the
WinSock functions: send(), sendto(), setsockopt() Additional functions: Any function that does network I/O: recv(), recvfrom(), FD_READ, FD_WRITE See also: WSAECONNABORTED, WSAECONNRESET, WSAETIMEDOUT WSAENETUNREACH (10051) Network is unreachable.
It's just a fact of life in the computer world. WinSock functions:
WinSock description: Same as Berkeley. "You can't make a silk purse from a sow's ear." Detailed descriptions: accept(), listen(): socket is not of type that supports connection-oriented service. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. WinSock description: a quick comparison to the Berkeley counterpart, and a long description of WinSock error. Berkeley description: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was supplied.
Ping the remote host you were connected to. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable. WinSock description: Unlike Berkeley Sockets, in WinSock WSAEALREADY means that the asynchronous operation you attempted to cancel has already been canceled.
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 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. Berkeley description: A message sent on a socket was larger than the internal message buffer or some other network limit. a "high-level" protocol).
WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket. Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). Most of the time people don't even realize this is going on. The occurrence of an unlisted error can provide extra detail.
recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that. For instance, even if you request to send() a few bytes of data on a newly created TCP connection, send() could fail with WSAEWOULDBLOCK (if, say, the network system has a
