// Standard Configuration Structures
//
// Although the Configuration functions are generic, NETTOOLS expects
// to be able to access a configuration with certain pre-defined
// configuration tags.
//
// If a system needs to use the Service functions of NetTools, it must
// provide service providers to implement the configuration specification
// defined here.

// Note: *** Default Configuration Handle Required ***
//
// NetTools uses the default configuration handle for things like
// DHCP client, DHCP server, DNS, etc.. This handle should be
// set by calling CfgSetDefault() before using NetTools

// Common Service Arguments
//
// All services have a common argument structure which dictates their
// operation under certain circumstances. Also, the use can install a
// callback for services to be informed on status change. The callback
// function is defined as:
//
//    CallbackFunction( uint Item, uint Status, uint code, HANDLE hCfgEntry )
//       Item      = Item value of entry changed
//       Status    = New status
//       Code      = Report code (if any)
//       hCfgEntry = Non-Ref'd HANDLE to entry with status change
//
//  The value of "Status" does not proceed past "ENABLED". For Task
//  specific information, the standard NETTOOLS report code is used.
