the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail. Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a WinSock DLL to send a DNS "A" record query An invalid or inconsistent flowspec was found in the QoS provider-specific buffer. No more results can be returned by the WSALookupServiceNext function.
A socket already has a type (a protocol), and each sockaddr structure has an address family field to define its format. See also: WSAEAFNOSUPPORT WSAEPROCLIM (10067) Too many processes. Is the router up and running (check by pinging it, and then ping an address on the other side of it)? WSASYSNOTREADY 10091 Network subsystem is unavailable.
Winsock Error Windows 7
recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is 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. That's about one-quarter of the error values that aren't even used!
That they are not trying to use more than one Windows Sockets implementation simultaneously. It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned). All Rights Reserved. What Is A Socket Error The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server).
This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. Winsock Error 10054 This could be due to an out of memory error or to an internal QoS provider error. It also has a specific meaning for setsockopt(). WinSock functions:
The file handle reference is no longer available. Wsaeconnaborted 10053 WinSock description: Same as Berkeley. WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.
- WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count.
- Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH.
- WSAEALREADY 10037 Operation already in progress.
Winsock Error 10054
WinSock description: Almost same as Berkeley. The WinSock implementation was unable to allocate additional memory to accommodate the function request. Winsock Error Windows 7 This is what occurs in Berkeley Sockets. Wsagetlasterror 0 Developer suggestions: Always check the return value from a memory allocation to be sure it succeeded.
Too many references to some kernel object. Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. For example, this error is returned if sendto is called with the remote address of ADDR_ANY. However, it also occurs when an application passes an invalid pointer value. Wsaenetunreach
If you used a hostname, did it resolve to the correct address? The high 2 bits of the upper word are used * to encode the in/out status of the parameter; for now * we restrict parameters to at most 128 bytes. */ The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. 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.
If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address. Socket Error 10054 Connection Reset By Peer WSAEPROVIDERFAILEDINIT 10106 Service provider failed to initialize. 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
WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: Any function that does network I/O: recv(), recvfrom(), send(), FD_READ, FD_WRITE See also: WSAEHOSTUNREACH WSAENOBUFS (10055) No buffer space available.
WSAEOPNOTSUPP (10045) Operation not supported. Any of the WinSock name resolution functions can fail with this error. Although the specification doesn't list an error for a function, it does allow for it. Wsaenotsock 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
WinSock description: Same as Berkeley for host resolution. Client applications usually need not call bind at all—connect chooses an unused port automatically. Berkeley description: No equivalent in 4.3 BSD or compatible operating systems. WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.
TCP/IP scenario: description of the TCP/IP protocol suite network traffic (i.e. 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"). Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. Other information varies between different errors.
A required address was omitted from an operation on a socket. No connection could be made because the target computer actively refused it. WSAEACCES 10013 Permission denied. Request refused: name server refuses to satisfy your query for policy reasons.
Ping a host on the same subnet as the host you were connected to (if you know one). Typically, only one usage of each socket address (protocol/IP address/port) is permitted. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for.
