100Routine Description:
101 Send an IRP_MJPNP/IRP_MN_QUERY_INTERFACE irp to a device object and its
102 attached stack.
103
104Arguments:
105 TargetDevice - device to send the query to.
106
107 InterfaceType - The type of interface to query for
108
109 Interface - The interface to fill out
110
111 Size - Size of Interface in bytes
112
113 Version - Version of the interface to be queried
114
115 InterfaceSpecificData - Addtional interface data to be queried
116
117
118Return Value:
119 NTSTATUS as indicated by the handler of the QI with in the device stack,
120 STATUS_NOT_SUPPORTED if the QI is not handled.

157Routine Description:
158 Marks the structure as embedded and sets the configuration. This is used
159 for FxQueryInterface structs which are embedded in other structures because
160 at contruction time the Config is not available yet.
161
162 By marking as embedded, FxPkgPnp will not free the structure when it deletes
163 the query interface chain.
164
165Arguments:
166 Config - how the interface behaves
167
168 Interface - the interface that is exported
169
170Return Value:
171 None
