Routine Description:
|
||
|
|
Send an IRP_MJPNP/IRP_MN_QUERY_INTERFACE irp to a device object and its
|
||
|
|
attached stack.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
TargetDevice - device to send the query to.
|
||
|
|
|
||
|
|
InterfaceType - The type of interface to query for
|
||
|
|
|
||
|
|
Interface - The interface to fill out
|
||
|
|
|
||
|
|
Size - Size of Interface in bytes
|
||
|
|
|
||
|
|
Version - Version of the interface to be queried
|
||
|
|
|
||
|
|
InterfaceSpecificData - Addtional interface data to be queried
|
||
|
|
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
NTSTATUS as indicated by the handler of the QI with in the device stack,
|
||
|
|
STATUS_NOT_SUPPORTED if the QI is not handled.

Routine Description:
|
||
|
|
Marks the structure as embedded and sets the configuration. This is used
|
||
|
|
for FxQueryInterface structs which are embedded in other structures because
|
||
|
|
at contruction time the Config is not available yet.
|
||
|
|
|
||
|
|
By marking as embedded, FxPkgPnp will not free the structure when it deletes
|
||
|
|
the query interface chain.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
Config - how the interface behaves
|
||
|
|
|
||
|
|
Interface - the interface that is exported
