Socket Error Code






ErrorCode en-US Info zh-CN Info Details
6 Specified event object handle is invalid. 指定事件对象句柄无效 An application attempts to use an event object, but the   specified handle is not valid. Note that this error is returned by the   operating system, so the error number may change in future releases of   Windows.
8 Insufficient memory available. 可用内存不足 An application used a Windows Sockets function that directly   maps to a Windows function. The Windows function is indicating a lack of   required memory resources. Note that this error is returned by the operating   system, so the error number may change in future releases of Windows.
87 One or more parameters are invalid. 一个或多个参数无效 An application used a Windows Sockets function which directly   maps to a Windows function. The Windows function is indicating a problem with   one or more parameters. Note that this error is returned by the operating   system, so the error number may change in future releases of Windows.
995 Overlapped operation aborted. 重复操作已被中止 An overlapped operation was canceled due to the closure of the   socket, or the execution of the SIO_FLUSH command in WSAIoctl. Note that this   error is returned by the operating system, so the error number may change in   future releases of Windows.
996 Overlapped I/O event object not in signaled state. 重复的I/O事件还未完成 The application has tried to determine the status of an overlapped   operation which is not yet completed. Applications that   use WSAGetOverlappedResult (with the fWait flag set   to FALSE) in a polling mode to determine when an overlapped operation   has completed, get this error code until the operation is complete. Note that   this error is returned by the operating system, so the error number may   change in future releases of Windows.
997 Overlapped operations will complete later. 重复操作即将完成 The application has initiated an overlapped operation that   cannot be completed immediately. A completion indication will be given later   when the operation has been completed. Note that this error is returned by   the operating system, so the error number may change in future releases of   Windows.
10004 Interrupted function call. (阻塞)函数中断 A   blocking operation was interrupted by a call to WSACancelBlockingCall.
10009 File handle is not valid. 文件句柄无效 The file handle supplied is not valid.
10013 Permission denied. 访问套接字权限被拒绝 An attempt was made to access a   socket in a way forbidden by its access permissions. An example is using a   broadcast address for sendto without broadcast permission being set using   setsockopt(SO_BROADCAST).
    Another possible reason for the WSAEACCES error is that when the bind   function is called (on Windows NT 4.0 with SP4 and later), another   application, service, or kernel mode driver is bound to the same address with   exclusive access. Such exclusive access is a new feature of Windows NT 4.0   with SP4 and later, and is implemented by using the SO_EXCLUSIVEADDRUSE   option.
10014 Bad address. 错误的套接字地址 The system detected an invalid pointer address in attempting   to use a pointer argument of a call. This error occurs if an application   passes an invalid pointer value, or if the length of the buffer is too small.   For instance, if the length of an argument, which is a sockaddr structure, is   smaller than the sizeof(sockaddr).
10022 Invalid argument. 参数无效 Some invalid argument was supplied (for   example, specifying an invalid level to the setsockopt function). In some instances, it also refers to the   current state of the socket—for instance, calling accept on a socket that is not   listening.
10024 Too many open files. 套接字数目超出限制 Too many open sockets. Each implementation may have a maximum   number of socket handles available, either globally, per process, or per   thread.
10035 Resource temporarily unavailable. 资源暂时不可用 This error is returned from operations on nonblocking sockets   that cannot be completed immediately, for example recv when no data is queued   to be read from the socket. It is a nonfatal error, and the operation should   be retried later. It is normal for WSAEWOULDBLOCK to be reported as the   result from calling connect on a nonblocking SOCK_STREAM socket, since some   time must elapse for the connection to be established.
10036 Operation now in progress. 操作正在执行 A blocking operation is currently executing. Windows Sockets   only allows a single blocking operation—per- task or thread—to be   outstanding, and if any other function call is made (whether or not it   references that or any other socket) the function fails with the   WSAEINPROGRESS error.
10037 Operation already in progress. 操作已在执行队列中 An operation was attempted on a nonblocking socket with an   operation already in progress—that is, calling connect a second time on a   nonblocking socket that is already connecting, or canceling an asynchronous   request (WSAAsyncGetXbyY) that has already been canceled or completed.
10038 Socket operation on nonsocket. 尝试在一个非套接字上操作 An operation was attempted on something that is not a socket.   Either the socket handle parameter did not reference a valid socket, or for   select, a member of an fd_set was not valid.
10039 Destination address required. 无目标地址 A required address was omitted from an operation on a socket.   For example, this error is returned if sendto is called with the remote   address of ADDR_ANY.
10040 Message too long. 消息长度超出限制 A message sent on a datagram socket was larger than the   internal message buffer or some other network limit, or the buffer used to   receive a datagram was smaller than the datagram itself.
10041 Protocol wrong type for socket. 当前套接字不支持此协议类型 A protocol was specified in the socket function call that does   not support the semantics of the socket type requested. For example, the ARPA   Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM.
10042 Bad protocol option. 错误的协议操作 An unknown, invalid or unsupported option or level was   specified in a getsockopt or setsockopt call.
10043 Protocol not supported. 系统不支持此协议 The requested protocol has not been configured into the   system, or no implementation for it exists. For example, a socket call   requests a SOCK_DGRAM socket, but specifies a stream protocol.
10044 Socket type not supported. 不支持此套接字类型 The support for the specified socket type does not exist in   this address family. For example, the optional type SOCK_RAW might be   selected in a socket call, and the implementation does not support SOCK_RAW   sockets at all.
10045 Operation not supported. 尝试操作不支持的对象引用 The attempted operation is not supported for the type of   object referenced. 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.
10046 Protocol family not supported. 系统不支持此协议(同10043) The protocol family has not been configured into the system or   no implementation for it exists. This message has a slightly different   meaning from WSAEAFNOSUPPORT. However, it is interchangeable in most cases,   and all Windows Sockets functions that return one of these messages also   specify WSAEAFNOSUPPORT.
10047 Address family not supported by protocol family. 使用的地址与被请求的协议不兼容 An address incompatible with the requested protocol was used.   All sockets are created with an associated address family (that is, AF_INET   for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM).   This error is returned if an incorrect protocol is explicitly requested in   the socket call, or if an address of the wrong family is used for a socket,   for example, in sendto.
10048 Address already in use. 绑定地址已存在 Typically, only one usage of each socket address (protocol/IP   address/port) is permitted. 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 properly, or one that is   still in the process of closing. For server applications that need to bind   multiple sockets to the same port number, consider using setsockopt   (SO_REUSEADDR). Client applications usually need not call bind at all—connect   chooses an unused port automatically. When bind is called with a wildcard   address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until   the specific address is committed. This could happen with a call to another   function later, including connect, listen, WSAConnect, or WSAJoinLeaf.
10049 Cannot assign requested address. 不可分配地址 The requested address is not valid in its context. This   normally results from an attempt to bind to an address that is not valid for   the local computer. This can also result from connect, sendto, WSAConnect,   WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a   remote computer (for example, address or port 0).
10050 Network is down. 网络断开 A socket operation encountered a dead network. 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.
10051 Network is unreachable. 网络连接已断开 A socket operation was attempted to an unreachable network.   This usually means the local software knows no route to reach the remote   host.
10052 Network dropped connection on reset. 心跳检测已断开连接 The connection has been broken due to keep-alive activity   detecting a failure while the operation was in progress. It can also be   returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a   connection that has already failed.
10053 Software caused connection abort. 软件导致连接中止 An established connection was aborted by the software in your   host computer, possibly due to a data transmission time-out or protocol   error.
10054 Connection reset by peer. 远程主机强制断开连接 An existing connection was forcibly closed by the remote host.   This normally results if the peer application on the remote host is suddenly   stopped, the host is rebooted, the host or remote network interface is   disabled, or the remote host uses a hard close (see setsockopt for more   information on the SO_LINGER option on the remote socket). This error may   also result if a connection was broken due to keep-alive activity detecting a   failure while one or more operations are in progress. Operations that were in   progress fail with WSAENETRESET. Subsequent operations fail with   WSAECONNRESET.
10055 No buffer space available. 缓存已满 An operation on a socket could not be performed because the   system lacked sufficient buffer space or because a queue was full.
10056 Socket is already connected. 套接字连接已存在 A connect request was made on an already-connected socket.   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 a legal   occurrence.
10057 Socket is not connected. 套接字未连接 A request to send or receive data was disallowed because the   socket is not connected and (when sending on a datagram socket using sendto)   no address was supplied. Any other type of operation might also return this   error—for example, setsockopt setting SO_KEEPALIVE if the connection has been   reset.
10058 Cannot send after socket shutdown. 不能在关闭套接字后收发信息 A request to send or receive data was disallowed because the   socket had already been shut down in that direction with a previous shutdown   call. By calling shutdown a partial close of a socket is requested, which is   a signal that sending or receiving, or both have been discontinued.
10059 Too many references. 过多的引用 Too many references to some kernel object.
10060 Connection timed out. 连接超时 A connection attempt failed because the connected party did   not properly respond after a period of time, or the established connection   failed because the connected host has failed to respond.
10061 Connection refused. 尝试连接被拒绝或服务未启动 No connection could be made because the target computer   actively refused it. 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.
10062 Cannot translate name. 不能翻译名称 Cannot translate a name.
10063 Name too long. 名称过长 A name component or a name was too long.
10064 Host is down. 主机中止 A socket operation failed because the destination host is   down. A socket operation encountered a dead host. Networking activity on the   local host has not been initiated. These conditions are more likely to be   indicated by the error WSAETIMEDOUT.
10065 No route to host. 无法到达主机 A socket operation was attempted to an unreachable host. See   WSAENETUNREACH.
10066 Directory not empty. 不能移除非空目录 Cannot remove a directory that is not empty.
10067 Too many processes. 进程数目超出限制 A Windows Sockets implementation may have a limit on the   number of applications that can use it simultaneously. WSAStartup may fail   with this error if the limit has been reached.
10068 User quota exceeded. 用户超出配额 Ran out of user quota.
10069 Disk quota exceeded. 磁盘超出配额 Ran out of disk quota.
10070 Stale file handle reference. 不可用的文件句柄 The file handle reference is no longer available.
10071 Item is remote. 本地不可用 The item is not available locally.
10091 Network subsystem is unavailable. 网络子系统不可用 This error is returned by   WSAStartup if the Windows Sockets implementation cannot function at this time   because the underlying system it uses to provide network services is   currently unavailable. Users should check:
    That the appropriate Windows Sockets DLL file is in the current path.
    That they are not trying to use more than one Windows Sockets   implementation simultaneously. 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.
    The Windows Sockets implementation documentation to be sure all necessary   components are currently installed and configured correctly.
10092 Winsock.dll version out of range. Winsock.dll版本超出支持范围 The current Windows Sockets implementation does not support   the Windows Sockets specification version requested by the application. Check   that no old Windows Sockets DLL files are being accessed.
10093 Successful WSAStartup not yet performed. 当前进程无法使用套接字资源 Either the application has not called WSAStartup or WSAStartup   failed. The application may be accessing a socket that the current active   task does not own (that is, trying to share a socket between tasks), or   WSACleanup has been called too many times.
10101 Graceful shutdown in progress. 正在关闭 Returned by WSARecv and WSARecvFrom to indicate that the   remote party has initiated a graceful shutdown sequence.
10102 No more results. 没有更多的返回值 No more results can be returned by the WSALookupServiceNext   function.
10103 Call has been canceled. 调用被取消,由于其正在运行 A call to the WSALookupServiceEnd function was made while this   call was still processing. The call has been canceled.
10104 Procedure call table is invalid. 过程调用表无效 The service provider procedure call table is invalid. A   service provider returned a bogus procedure table to Ws2_32.dll. This is   usually caused by one or more of the function pointers being NULL.
10105 Service provider is invalid. 服务提供者无效 The requested service provider is invalid. This error is   returned by the WSCGetProviderInfo and WSCGetProviderInfo32 functions if the   protocol entry specified could not be found. This error is also returned if   the service provider returned a version number other than 2.0.
10106 Service provider failed to initialize. 服务提供者的DLL加载失败 The requested service provider could not be loaded or   initialized. This error is returned if either a service provider's DLL could   not be loaded (LoadLibrary failed) or the provider's WSPStartup or NSPStartup   function failed.
10107 System call failure. 系统调用失败 A system call that should never   fail has failed. This is a generic error code, returned under various   conditions.
    Returned when a system call that should never fail does fail. For example,   if a call to WaitForMultipleEvents fails or one of the registry functions   fails trying to manipulate the protocol/namespace catalogs.
    Returned when a provider does not return SUCCESS and does not provide an   extended error code. Can indicate a service provider implementation error.
10108 Service not found. 在指定的命名空间中找不到服务 No such service is known. The service cannot be found in the   specified name space.
10109 Class type not found. 找不到指定的类 The specified class was not found.
10110 No more results. 没有更多的返回值 No more results can be returned by the WSALookupServiceNext   function.
10111 Call was canceled. 调用被取消,由于其正在运行 A call to the WSALookupServiceEnd function was made while this   call was still processing. The call has been canceled.
10112 Database query was refused. 数据库查询被拒绝 A database query failed because it was actively refused.
11001 Host not found. 指定的主机名未找到 No such host is known. The name is not an official host name   or alias, or it cannot be found in the database(s) being queried. This error   may also be returned for protocol and service queries, and means that the   specified name could not be found in the relevant database.
11002 Nonauthoritative host not found. 未收到授权主机响应 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. A retry at some time later may be successful.
11003 This is a nonrecoverable error. 在查找数据中出现未知错误 This indicates that some sort of nonrecoverable error occurred   during a database lookup. This may be because the database files (for   example, BSD-compatible HOSTS, SERVICES, or PROTOCOLS files) could not be   found, or a DNS request was returned by the server with a severe error.
11004 Valid name, no data record of requested type. 主机名存在,但地址解析失败 The requested name is valid and was found in the database, but   it does not have the correct associated data being resolved for. The usual   example for this is a host name-to-address translation attempt (using   gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name   Server). An MX record is returned but no A record—indicating the host itself   exists, but is not directly reachable.
11005 QoS receivers. 至少收到一个或多个QoS预约 At least one QoS reserve has arrived.
11006 QoS senders. 至少一个QoS发送路径已经到来 At least one QoS send path has arrived.
11007 No QoS senders. 没有QoS发送者 There are no QoS senders.
11008 QoS no receivers. 没有QoS接收者 There are no QoS receivers.

11010 QoS admission error. QoS缺乏资源 A QoS error occurred due to lack of resources.
11011 QoS policy failure. QoS请求策略资源被拒绝 The QoS request was rejected because the policy system   couldn't allocate the requested resource within the existing policy.
11012 QoS bad style. 未知或冲突的QoS样式 An unknown or conflicting QoS style was encountered.
11013 QoS bad object. 错误的QoS对象 A problem was encountered with some part of the filterspec or   the provider-specific buffer in general.
11014 QoS traffic control error. QoS流量控制器错误 An error with the underlying traffic control (TC) API as the   generic QoS request was converted for local enforcement by the TC API. This   could be due to an out of memory error or to an internal QoS provider error.
