Winsock Error 10045
Developer suggestions: for protocols and services consider using a hard-coded value for the protocol number or service port number in case your resolution attempt fails, and you can have your cake Detailed description: select(): fails with WSAENOTSOCK if any socket in an fd_set is an invalid socket handle. For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file. Try a traceroute to the destination address to check that all the routers are functioning. http://pdctoday.com/socket-error/winsock-2-0-error.php
WSAENOTSOCK 10038 Socket operation on nonsocket. 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. Why does Wolfram Alpha say the roots of a cubic involve square roots of negative numbers, when all three roots are real? 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.

This means another type of request to the name server will result in an answer. By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued. An unknown or conflicting QoS style was encountered.

WSAEINTR (10004) Interrupted function call. Missing system data files can be a real risk to the health and wellbeing of any pc. Some Winsock service providers set a limit on the number of processes that can simultaneously access them. 10091WSASYSNOTREADY Network subsystem is unavailable. Socket Error 10054 Connection Reset By Peer 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").

Detailed descriptions: connect(): the operation is underway, but as yet incomplete. http://www.ibm.com/support/docview.wss?uid=swg21548946 In WinSock it means a blocking operation was interrupted by a call to WSACancelBlockingCall. Socket Error 10054 It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. What Is A Socket Error However, it also occurs when an application passes an invalid pointer value.
Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. http://pdctoday.com/socket-error/winsock-ftp-error.php 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. It indicates that a nonrecoverable error has occurred and the operation should be tried again. 11004WSANO_DATA No data record of the requested type found. If so, is there an older DLL in a directory in the path ahead of the directory containing the newer DLL? Socket Error 10049
WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter. User suggestions: Don't try running two of the same types of server applications on the same machine. 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(). weblink WSAEHOSTDOWN 10064 Host is down.
WSAEPROTOTYPE 10041 Protocol wrong type for socket. Winsock Error 10061 If you used a hostname, did it resolve to the correct address? WinSock description: Same as Berkeley.
In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets.
This could indicate the failure of the network stack, the network interface, or the local network. 10051WSAENETUNREACH Network is unreachable. connect(), send(), recv(), et cetera). The v1.1 WinSock specification doesn't list any errors for these functions. Socket Error 10061 Connection Refused Note that this occurs only on the data-flow direction that has been shut down.
