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. An invalid or unrecognized service type was found in the QoS flowspec. But that's not to say you shouldn't still be prepared. An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.
Usually this occurs when a socket descriptor to a socket that cannot support this operation is trying to accept a connection on a datagram socket. 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 WSA_QOS_EPOLICYOBJ 11025 Invalid QoS policy object. a "high-level" protocol).
Socket Error 10054
WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object. User suggestions: see WSAHOST_NOT_FOUND for details. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. Now that you know what does WSAENOPROTOOPT 10042 (0X273A) mean, you may avoid this kind of system errors in the future.
In this case, the 2nd application will fail with WSAEADDRINUSE. For example, you shouldn't necessarily expect to be able to use NS addresses with ARPA Internet protocols. Any of the WinSock name resolution functions can fail with this error. Socket Error 10054 Connection Reset By Peer I modified the sockopt.c test to bind the UDP socket to an address (INADDR_ANY, port 0). /cvsroot/mozilla/nsprpub/pr/tests/sockopt.c, revision 3.8 (Internal repository /m/src/ns/nspr20/pr/tests/sockopt.c, revision 2.7) Comment 7 srinivas 1999-12-30 18:02:59 PST Marking
It may also indicate you are not closing the applications properly. What Is A Socket Error The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock. Berkeley description: A socket operation failed because the destination host was down. Typically, the Wsaenoprotoopt error message may be brought on by Windows system file damage.
after the first failed with WSAEWOULDBLOCK). Socket Error 10049 WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address. So I have no idea why we can't set the IP_MULTICAST_TTL option.
What Is A Socket Error
Instead, let the network system assign the local port (very few application protocols require a client to bind to a specific port number or port number range). User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. Socket Error 10054 It makes sense because if I include
WinSock functions: With a datastream socket: connect() and FD_CONNECT WSAAsyncelect() notification message. An application used a Windows Sockets function which directly maps to a Windows function. Berkeley description: A connection abort was caused internal to your host machine. This could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself. Socket Error 10038
User suggestions: Chances are the network subsystem is misconfigured or inactive. Right now it is mapped to PR_INVALID_ARGUMENT_ERROR. WSAELOOP 10062 Cannot translate name. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!
WSA_OPERATION_ABORTED 995 Overlapped operation aborted. Wsagetlasterror 0 The WinSock API does not provide any way to select specific name resolution protocols, server address, or record type. If there is more than one Winsock DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.
WSANO_DATA 11004 Valid name, no data record of requested type.
WSAESOCKTNOSUPPORT 10044 Socket type not supported. See also: These point to other errors that are similar. Detailed descriptions: the specific meanings that some WinSock functions have for some errors. Wsaeconnreset 10054 Check the destination address you are using.
For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR). This error is relevant to connect(), but not to send() or sendto() as it is in Berkeley Sockets. This has no network-relevant analog (although the "inode" reference could refer to a network file system entry). WSAEAFNOSUPPORT 10047 Address family not supported by protocol family.
WSAEPROVIDERFAILEDINIT 10106 Service provider failed to initialize. This error occurs if an application attempts to bind a socket to an IP address/port that has already been used for an existing socket, or a socket that was not closed An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockopt call. ) As the same code works well in the oher application, I guess that there's 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
If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet Operations that were in progress fail with WSAENETRESET. 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 I have the code already running with your help.
Berkeley description: The quota system ran out of table entries. It means that there is a blocking operation outstanding. WinSock description: Same as Berkeley. A required address was omitted from an operation on a socket.
Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. WinSock functions: accept(), close socket(), connect(), recv(), recvfrom(), send(), sendto(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() WSAHOST_NOT_FOUND (11001) Host not found Berkeley description: No such host is known.

A call to the WSALookupServiceEnd function was made while this call was still processing. Thx in advance BTW: I'm using Microsoft Visual C++ 6.0 with Win2k Reply With Quote September 10th, 2004,05:33 PM #4 kuphryn View Profile View Forum Posts Visit Homepage Elite Member Power
