|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
ControlSetKeyHandle - supplies handle to open registry key for current
|
||
|
|
control set (ie, HKEY_LOCAL_MACHINE\CurrentControlSet).
|
||
|
|
|
||
|
|
HwComponents - supplies the address of the master hardware components
|
||
|
|
array.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
