Wsa Error 10045

Contents

For information, see the Handling Winsock Errors topic. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. The operation encountered a dead network. For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol.WSAEPROTOTYPE (10041)Protocol wrong type for socket.A protocol was specified in the socket function call that does not support

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 A problem was encountered with some part of the filterspec or the provider-specific buffer in general. Applications should check for both this error and WSAENOMORE. 10111WSA_E_CANCELLED Operation canceled. 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.

Socket Error 10054

WinSock description: No equivalent. WSASYSNOTREADY 10091 Network subsystem is unavailable. This usually results from trying to connect to a service that is inactive on the foreign host - i.e.

Each implementation may have a maximum number of socket handles available, either globally, per process or per thread. -------------------------------------------------------------------------------- WSAENOTSOCK Error Number: 10038 Socket operation on non-socket. See also: WSANO_DATA, WSANO_RECOVERY, WSATRY_AGAIN WSANOTINITIALISED (10093) Successful WSAStartup() not yet performed Berkeley description: No equivalent. WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links. Socket Error 10054 Connection Reset By Peer WinSock description: Same as Berkeley.

The file handle reference is no longer available. Socket Error 10053 A socket operation was attempted to an unreachable host. -------------------------------------------------------------------------------- WSAEINVAL Error Number: 10022 Invalid argument. For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). Join them; it only takes a minute: Sign up c++ UDP socket error 10045 up vote 3 down vote favorite 2 SOLVED The error was assuming that UDP and TCP have

The specified socket parameter refers to a file, not a socket. Socket Error 11004 The error occurs with the socket() function, which takes the socket type (protocol) and address family as input parameters. 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. WSAEHOSTDOWN 10064 Host is down.

Socket Error 10053

Some error codes defined in the Winsock2.h header file are not returned from any function. It helps to think a little more carefully. Socket Error 10054 The ICMP message means that the 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). Socket Error 10049 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

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. Developer suggestion: are you trying to use an optional feature? The WinSock API does not provide access to the Network File System application protocol, so this error is irrelevant to WinSock. This error indicates either unknown or conflicting style types. Socket Error Codes Linux

I don't see anything in this code that would cause that error on bind(). Since Windows Sockets is practically a clone of Berkeley Sockets, and the rule of thumb is "when in doubt, defer to Berkeley", we can adopt the Berkeley Software Distribution error text In some instances, it also refers to the current state of the socket—for instance, calling accept on a socket that is not listening. WinSock functions: WSAENETDOWN (10050) Network is down.

This error occurs if an program passes an invalid pointer value, or if the length of the buffer is too small.

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"). WSAEISCONN 10056 Socket is already connected. The support for the specified socket type does not exist in this address family. Socket Error 11001 User suggestions: see WSAHOST_NOT_FOUND for details.

This error is also generated when the specified buffer is too small. 10022WSAEINVAL Invalid argument. A blocking operation is currently executing. you're trying to share a socket between tasks). A socket operation failed because the destination host is down.

All sockets are created with an associated "address family" (i.e. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. Applications should check for both this error and WSA_E_CANCELLED. 10104WSAEINVALIDPROCTABLE The procedure call table is invalid. Windows Sockets Error Codes Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns.

Whether to handle it as a fatal error or non-fatal error depends on the application and the context, so it's entirely up to you to decide. This error can also occur when calling socket or WSASocket and requesting an invalid combination of address family, socket type, and protocol. 10048WSAEADDRINUSE Address already in use. WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other The error can also occur in an attempt to rename a file or directory or to remove an existing directory.

For protocol and services resolution, the name or number was not found in the respective database.

WSAETOOMANYREFS 10059 Too many references. before calling connect() or accept()).

WSA_QOS_EPOLICYOBJ 11025 Invalid QoS policy object. Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). WSA_IO_INCOMPLETE 996 Overlapped I/O event object not in signaled state. QOS applications can establish different filter styles for a given session.

See WSAENETUNREACHWSAEINPROGRESS (10036)Operation now in progress.A blocking operation is currently executing. WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: It seems odd that the v1.1 specification doesn't ascribe this error to the function bind(). WinSock functions: WSAEFAULT (10014) Bad address. WSAEHOSTUNREACH 10065 No route to host.
