The Windows Sockets provider for NetBIOS is not directly related to the NetBIOS programming interface. The Windows Sockets provider for NetBIOS only supports sockets where the type parameter is set to SOCK_DGRAM. The Windows Sockets provider for NetBIOS is not supported on 64-bit versions of windows. This provider is installed by default on 32-bit versions of Windows. The Windows Sockets provider for NetBIOS is supported on 32-bit versions of Windows. This address family is only supported if the Windows Sockets provider for NetBIOS is installed. This address family is not supported on Windows Vista and later. This address family is only supported if the AppleTalk protocol is installed.

The table below lists common values for address family although many other values are possible. Other options for address family (AF_NETBIOS for use with NetBIOS, for example) are supported if a Windows Sockets service provider for the address family is installed. The values currently supported are AF_INET or AF_INET6, which are the Internet address family formats for IPv4 and IPv6.

Note that the Ws2def.h header file is automatically included in Winsock2.h, and should never be used directly. Possible values for the address family are defined in the Ws2def.h header file. The address family specification for the socket. For more information, see the Windows Driver Kit documentation for the EPROCESS structure. This is an opaque structure that serves as the process object for a process. The EPROCESS address of the process that owns the related socket. The Winsock AFD driver caused this event to occur (setting a socket option, for example). This usually indicates a data notification. The TCP/IP driver caused this event to occur. The Winsock AFD driver took an internal action (aborting a connection, for example). The following table lists the possible values for the EnterExit parameter: Value const EVENT_DESCRIPTOR AFD_EVENT_CREATE = The AFD_EVENT_CREATE event is a Winsock network tracing event for a socket creation operation.
