Furthermore, it is not possible for an application to assign a new value to errno. Although error constants consistent with Berkeley Sockets 4. Thus, a better version of the preceding source code fragment is:.
The original Winsock 1. Windows Sockets 2 added functions and features with other Windows Sockets error codes returned in addition to those listed in the original Winsock specification. Additional functions have been added over time to enhance Winsock for use by developers. For example, new name service functions getaddrinfo and getnameinfo , for example were added that support both IPv6 and IPv4 on Windows XP and later.
Some of the older IPv4-only name service functions the getXbyY class of functions, for example have been deprecated. A complete list of possible error codes returned by Windows Sockets functions is given in the section on Windows Sockets Error Codes. Porting Socket Applications to Winsock. Windows Sockets Error Codes. Connection timed out.
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. Connection refused. 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.
Cannot translate name. Cannot translate a name. Name too long. A name component or a name was too long. Host is down. 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. No route to host. A socket operation was attempted to an unreachable host. Directory not empty. Cannot remove a directory that is not empty. Too many processes. 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. User quota exceeded. Ran out of user quota. Disk quota exceeded. Ran out of disk quota. Stale file handle reference. The file handle reference is no longer available. Item is remote. The item is not available locally. Network subsystem is unavailable. 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.
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. The current Windows Sockets implementation does not support the Windows Sockets specification version requested by the application.
Successful WSAStartup not yet performed. 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. Graceful shutdown in progress. No more results. Call has been canceled. The call has been canceled. Procedure call table is invalid. The service provider procedure call table is invalid. This is usually caused by one or more of the function pointers being NULL.
Service provider is invalid. The requested service provider is invalid. This error is also returned if the service provider returned a version number other than 2. Service provider failed to initialize. The requested service provider could not be loaded or initialized. System call failure. 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. Can indicate a service provider implementation error.
Service not found. No such service is known. The service cannot be found in the specified name space. Class type not found. The specified class was not found. Call was canceled. Database query was refused. A database query failed because it was actively refused. Host not found. 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.
Nonauthoritative host not found. 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. This is a nonrecoverable error. This indicates that some sort of nonrecoverable error occurred during a database lookup. Valid name, no data record of requested type. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for.
An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable. QoS receivers. At least one QoS reserve has arrived. QoS senders. This is old production code Has anybody been able to use the select built with x64?

The code you posted is unformatted and almost unreadable. Very few will attempt to read it in the state that it's in. March 21st, , AM 4. Re: Windows Sockets 64 bit Thanks Paul, first time posting code. Now have [code] tags inserted. Hopefully you can read my code easily now. To debug this I commented out the InitServer function because that is application specific. The listening socket is obtained from the GetAcceptSocket method.
And stepping through this with the debugger I have verified the listening socket is good. Remember, this stuff works compiled with win32 configuration. It only fails as x Just because I have had this in production for so long.
But the file descriptor of the listening socket is valid! And it does block when built as win I am really at my wits end on this. If I step into select, all I can look at is the assembly code.
So that is why I asked, has anybody been able to make select work in blocking mode waiting for a connection built as x64? March 21st, , AM 5.
