Syntax

    LONG NPA_Config (
       LONG   function,
       LONG   parameter0,
       LONG   parameter1,
       LONG   parameter2
       );

Parameters

Function 1 - Enable/Disable CDM Autoload

Parameter	Value
function	1
parameter0	0 = Disable autoload 1 = Enable autoload
parameter1	0
parameter2	0

Function 2 - Enable/Disable Autoscan

function	2
parameter0	0 = Disable autoscan 1 = Enable autoscan
parameter1	0
parameter2	0

Function 3 - Enable/Disable Sending of HACBs to HAMs

Parameter	Value
function	3
parameter0	Media Manager Object ID of the Adapter Object associated with the HAM. For more information on determining this ID number, refer to the Media Manager documentation.
parameter1	0 = Allow HACB requests to this HAM. 1 = Prevent HACB requests to this HAM.
parameter2	0

Function 4 - Return HACB Count on an Adapter

Parameter	Value
function	4
parameter0	Media Manager Object ID of the Adapter Object associated with the HAM. For more information on determining this ID number, refer to the NDK: Media Manager for NetWare 5.x and 6.x documentation.
parameter1	Address of a LONG where the count should be returned
parameter2	0

Function 5 - Return CDM Binding Information

This function returns the CDMs that are bound to a device in a find first - find next manner. The filter CDMs are returned first, than any enhancer CDMs, then finally the base CDM. A nonzero return code indicates that no more CDMs were found, and the information in the CDMInfoStruct is invalid.

Parameter	Value
function	5
parameter0	Media Manager Object ID of the Adapter Object associated with the HAM. Refer to the Media Manager documentation for more information on determining this ID number.
parameter1	Points to a LONG that represents the next CDM. The LONG that this address is pointing to must be initialized to -1 for the first CDM. NWPA automatically updates the pointer for the next call.
parameter2	Points to a CDMInfoStruct.

Function 6 - Reserved

Return Values

The following table lists return values and descriptions.

zero	Successful
nonzero	Unsuccessful

Remarks
