WSAStartup may fail with this error if the limit has been reached.WSAEPROTONOSUPPORT (10043)Protocol not supported.The requested protocol has not been configured into the system, or no implementation for it exists. In the case of this application , it does make sense to re-use the thread objects, but this is not going to be five minutes work. WSAECONNREFUSED (10061) Connection refused Connection refused: No connection could be made because the target machine actively refused it. Additional functions: Berkeley sockets connect returns this error on subsequent calls, after an initial call on a non-blocking socket. check my blog
Client programs usually need not call bind at all - connect will choose an unused port automatically.WSAEADDRNOTAVAIL (10049)Cannot assign requested address.The requested address is not valid in its context. port 0).WSAEAFNOSUPPORT (10047)Address family not supported by protocol family.An address incompatible with the requested protocol was used. Maybe the server must wait for the 1st 'send' from the client but I don't understand why that could be so ? I had considered maintaining a set of constantly open connections but, the Socket component is a derived version of the ICS one. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
For example, you can try to ping the server(s). An application attempted an input/output network function call before establishing an association with a remote socket (i.e. The only function that takes these two explicit parameters is socket.WSAENOPROTOOPT (10042) Bad protocol option A bad option or level was specified in a getsockopt(2) or setsockopt(2) call. it's not that hard actually.
I think this is a symptomatic of an underlying cause, and not a result of inter-thread behaviour. Typically though, Winsock generates this error when it receives a 'host unreachable' ICMP message from a router. It means that there is a blocking operation outstanding.It is also possible that Winsock might return this error after an application calls connect a second time on a non-blocking socket while Socket Error 10049 The Winsock description for this error is 'the specified socket type is not supported in this address family.' So, for example, you can expect this error if a Winsock implementation doesn't
if you do get it, then you probably missed some initialization code somewhere. Socket Error Codes Linux TCP/IP scenario: The local network system can generate this error if there is no a default route configured. To start with the application works fine for a while - reusing the threads as I expect. Most of them are for unix machines and for computer to computer communications where you control both side it does not matter too much, unless you land on one that windows
Will I encounter any problems as a recognizable Jew in India? Socket Error 11004 but it si possible. What appears to be happening is that during the socket's lifetime, its connected status changes from wsConnected to wsConnecting, perhaps multiple times.

Socket Error 10054 Winsock description: The Windows Sockets definition of this error is very different from Berkeley Sockets. Socket Error 10054 Connection Reset By Peer All this happens very quickly.
if so, do a search in your code and check if you somewhere disconnect the socket yourself. click site This is puzzling. you need a pool. repat do something (sendstr maybe) if wsagetlasterror=WSAEWOULDBLOCK then sleep(10) else break; until false; I am guessing that this is a limitation/bug in the windows Socket Error 10053
Ports over 1000 are used by the socket stuff. would that "fly" with your application? 0 Message Author Comment by:steve-west2008-03-03 I have a managing object that has the threads running in a private list. I think it's a speed issue - using a couple of threads and the problem takes longer to appear. news A socket already has a type (a protocol), and each sockaddr structure has an address family field to define its format.
WSAEPROTOTYPE (10041) Protocol wrong type for socket A protocol was specified that does not support the semantics of the socket type requested. Socket Error 10061 Connection Refused if this is true, then before each job you will have to chheck if ythe socket is connected or not, and connect it if it's not.

Try your ISP. If so, is there an older DLL in a directory in the path ahead of the directory containing the newer DLL? you can also create the threads only as needed, but that can be a little complicated, so I would leave it to when you have more free time - connection pooling. Winsock Error 10054 Fix Apparently a bug is that the sConnect does not set the lasterrorcode.
For instance, this error will occur if you try to run two applications that have FTP servers that both try to accept connections on port 21 (the standard FTP port). This error occurs if an program attempts to bind a socket to an IP address/port that has already been used for an existing socket, or a socket that wasn't closed properly, Its only purpose is to accept new connections from clients. http://jactionscripters.com/socket-error/winsock-error-10057-socket-is-not-presently-connected.php For example, you cannot use the ARPA Internet UDP protocol with type SOCK_STREAM.
