Module Name:

Abstract:

    This header file contains interface definitions for NT transport
    providers.  This interface is documented in the NT Transport
    Driver Interface (TDI) Specification, Version 2.

// Basic type used to represent an address at the transport level. There may
// be many addresses represented in a single address structure. If there are
// multiple addresses, a given provider must understand all of them or it can
// use none of them. Note that it is acceptible for the provider to not know
// how to use the address, as long as it knows the address type. Thus, a
// TCP/IP NetBIOS provider may know both NetBIOS and TCP/IP addresses, but
// use only the NetBIOS address; the TCP/IP address would (likely) be passed on
// to the TCP/IP provider.
