Can '\0' and NULL be used interchangeably? What would be the disadvantage to defining a class as a subclass of a list of itself? However, they don't need to set the WinSock error value, because there's only one reason for their failure: the input parameter was invalid. WSAEISCONN (10056) Socket is already connected. have a peek at these guys
WSAHOST_NOT_FOUND 11001 Host not found. Superscripts appear in various weird places in fractions Five-pointed crown alkane C25H40: does it exist? Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE on a connection that's already timed out. Should the sole user of a *nix system have two accounts?
User suggestions: This error indicates a shortage of resources on your system. A database query failed because it was actively refused. The 10'000 year skyscraper If a reviewer makes significant contributions to improving a paper, may he/she suggest becoming a coauthor? "Dare speak" vs. "dare to speak" vs "dares to speak" more Users should check: That the appropriate Windows Sockets DLL file is in the current path.
This extended error code can be different from the error code obtained from getsockopt when called with an optname parameter of SO_ERROR, which is socket-specific since WSAGetLastError is for all thread-specific Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. Browse other questions tagged c++ windows winsock or ask your own question. Socket Error 11004 This version doesn't exist.
Berkeley description: A socket operation encountered a dead network. Socket Error 10053 WinSock functions: accept(), bind(), getsockname(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), setsockopt(), shutdown(), WSAStartup(), WSAAsyncSelect(), WSACancelAsyncRequest(), WSACancelBlockingCall, FD_CONNECT Additional functions: Any WinSock function that takes input parameters that could be invalid Winsock Tutorial 5 Error handling with Winsock Previously we purposely omitted too much detail in error handling so as not to overwhelm newcomers. Based on the code you have provided, it appears that Socket::Accept() is returning a Socket instead of a Socket*.
WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported. Socket Error 10061 Connection Refused For example, the optional type SOCK_RAW might be selected in a socket call, and the implementation does not support SOCK_RAW sockets at all. The error occurs with the socket() function, which takes the socket type (protocol) and address family as input parameters. Is "she don't" sometimes considered correct form?
With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). A complete list of possible error codes returned by Windows Sockets functions is given in the section on Windows Sockets Error Codes. Socket Error Codes Linux You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it Socket Error 10049 Check that no old Windows Sockets DLL files are being accessed.
So, for example, if a WinSock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket() call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at http://devstude.net/socket-error/wsa-error-code-10093.php TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent. 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. Insuring A Girlfriends Motorcycle Why was The Hard Candy poster made in reverse to the plot? 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(). Here is a useable macro: #define MAKEWORD(low, high) ((WORD)(((BYTE)(low)) | (((WORD)((BYTE)(high))) << 8))) WinSock functions: WSAStartup(). [Go to Top] Errors in Numerical Order WSABASEERR (0) No Error WSAEINTR (10004) Interrupted system Berkeley description: This is a temporary condition and later calls to the same routine may complete normally (also known as EAGAIN error in Berkeley Software Distribution version 4.3) WinSock description: Same http://devstude.net/socket-error/wsa-error-code-183.php WinSock functions:
The address manipulation functions, inet_ntoa() andinet_addr(), can fail. Winsock Error 10054 Fix TCP/IP scenario: Most WinSock implementations use domain name system (DNS) protocol for hostname to address resolution, although a few use Network Information System (NIS). WinSock functions:
Any of the WinSock name resolution functions can fail with this error.
Not implemented: name server does not perform specified operation. WinSock description: Same as Berkeley. The error can also occur in an attempt to rename a file or directory or to remove an existing directory. Socket Error 11001 The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server).
WSAVERNOTSUPPORTED 10092 Winsock.dll version out of range. Remarks The WSAGetLastError function returns the last error that occurred for the calling thread. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. news all other functions: retry the operation again later since it cannot be satisfied at this time.
WinSock description: Same as Berkeley. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. WinSock functions: connect(), sendto(), FD_CONNECT WSAEDQUOT (10069) Disc quota exceeded. That means that on 32-bit systems, the addresses have to be multiples of 4, and on 64-bit systems, they must be multiples of 8.
If you are using a name server(s), check whether the server host(s) are up (e.g. WSAEAFNOSUPPORT 10047 Address family not supported by protocol family. Any application that uses a blocking socket or calls any blocking functions must handle this error. Windows 8.1 and Windows Server 2012 R2: This function is supported for Windows Store apps on Windows 8.1, Windows Server 2012 R2, and later.
If an application developer insists on using the BSD error codes for compatibility, then an application may choose to include a line of the form: C++ Copy #include
How would I translate “I slipped him a twenty” into German? This won't reveal too much unless you know the router addresses at the remote end, but it might help to identify if the problem is somewhere along the way. This reset could be generated locally by the network system when it detects a connection failure, or it might be received from the remote host (in TCP terms, the remote host An error with the underlying traffic control (TC) API as the generic QoS request was converted for local enforcement by the TC API.
WSANO_RECOVERY 11003 This is a nonrecoverable error. WSAEADDRINUSE (10048) Address already in use. Developer suggestion: The simple suggestion is "don't do that." No matter what value you use for the "how" parameter to the shutdown() function, you cannot send afterwards. This means, the version we are trying to use doesn't exist.
