Updated for Windows 7 and Windows Server 2008 R2
Microsoft Windows 7 and Windows Server 2008 R2 introduce new Windows Sockets programming elements.
The following existing Windows Sockets functions were enhanced to support additional options:
The following are new Windows Sockets options:
Dynamic send buffering for TCP was added on Windows 7 and Windows Server 2008 R2. As a result, the use of the SIO_IDEAL_SEND_BACKLOG_CHANGE and SIO_IDEAL_SEND_BACKLOG_QUERY IOCTLs are needed only in special circumstances. For more information, see SIO_IDEAL_SEND_BACKLOG_QUERY.
Updated for Windows Server 2008 and Windows Vista with Service Pack 1 (SP1)
Microsoft Windows Server 2008 and Windows Vista with Service Pack 1 (SP1) introduce new Windows Sockets programming elements.
The following are new Windows Sockets Ioctls:
These new Ioctls can be used by an application using TCP to determine the ideal value for the amount of data outstanding to send in order to achieve the best throughput for a connection. This is called the ideal send backlog (ISB) size.
Updated for Windows Server 2008
Microsoft Windows Server 2008 introduce new Windows Sockets programming elements.
