Generically, the error means the network system has run out of socket handles. WinSock functions:
This error signifies that an attempt was made to access a file (or, in some cases, a directory) in a way that is incompatible with the file's attributes. WSAENOTEMPTY 10066 Directory not empty. Anyway, there's a good practice to initialize socket descriptors to INVALID_SOCKET at the beginning. And, just because listen() takes 9 as a parameter, doesn't mean that the number of potential connections will be limited to 9 -- the *backlog* may be limited to 9. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.

Berkeley description: A message sent on a socket was larger than the internal message buffer or some other network limit. The following list describes the possible error codes returned by the WSAGetLastError function. WSAEDESTADDRREQ 10039 Destination address required. Socket Error 10054 Connection Reset By Peer Following accept() can return socket for second incoming connection etc.

The specified class was not found.
Berkeley description: A connect request was made on an already connected socket; or, a sendto() or sendmsg() request on a connected socket specified a destination when already connected. http://forums.codeguru.com/showthread.php?338917-Strange-winsock-error-10038 WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. Socket Error 10054 See also: WSANO_DATA, WSANO_RECOVERY, WSATRY_AGAIN WSANOTINITIALISED (10093) Successful WSAStartup() not yet performed Berkeley description: No equivalent. What Is A Socket Error WinSock description: Same as Berkeley.
An invalid QoS filter style was used. weblink WSASYSNOTREADY (10091) Network SubSystem is unavailable The Winsock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable. WSAENOPROTOOPT 10042 Bad protocol option. Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. Socket Error 10049
You can attempt to avoid the error by calling WSAIsBlocking() before making any WinSock function calls. When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. Been stuck on it for days. navigate here at all...
This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. Socket Error 10061 Connection Refused Been stuck on it for days. If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address.
Format error: Name server was unable to interpret the query. If numclients is less than or equal to zero, the loop won't execute (0 < numclients will be false from the start). Such an error is always a bug, it's not related to the real network activity/state and etc. Winsock Error 10061 A reserved policy element was found in the QoS provider-specific buffer. Requirements Header Winsock2.h; Winerror.h See also Error Codes - errno, h_errno and WSAGetLastError Handling Winsock Errors FormatMessage WSAGetLastError
WSAESOCKTNOSUPPORT 10044 Socket type not supported. 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 WSAEADDRNOTAVAIL (10049) Can't assign requested address Normally results from an attempt to create a socket with an address not on this machine. his comment is here Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid.
This error occurs if the sin_addr is INADDR_ANY (i.e. Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (for SOCK_STREAM sockets, the to parameter in sendto is ignored) although other implementations treat this as WinSock description: Same as Berkeley. A socket operation was attempted to an unreachable host.
This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. WSA_QOS_EPROVSPECBUF 11018 Invalid QoS provider buffer. Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. Given that ice is less dense than water, why doesn't it sit completely atop water (rather than slightly submerged)?
On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. For instance, if the length of an argument which is a struct sockaddr is smaller than sizeof(struct sockaddr).WSAEHOSTDOWN (10064)Host is down.A socket operation failed because the destination host was down. Berkeley description: A pathname lookup involved more than 8 symbolic links. WinSock functions:
It may also make explicit mention of other functions that can fail with this error. WSAEHOSTUNREACH 10065 No route to host. WinSock description: Same as Berkeley, and then some.
