The IoWMIDeviceObjectToProviderId routine translates the specified device object into the corresponding WMI Provider ID.
DeviceObject [in]Pointer to a device object.
IoWMIDeviceObjectToProviderId returns the WMI Provider ID associated with the specified device object.
IoWMIDeviceObjectToProviderId should be used when filling in the ProviderId member of the WNODE_HEADER structure in those cases when the WNODEHEADER structure is being initialized as part of a WNODE_EVENT_ITEM or WNODE_EVENT_REFERENCE structure. (If the WNODE_HEADER is being used for other purposes, ProviderId is reserved.)
When running on a 32-bit operating system, the provider ID and the device object are identical. When running on a 64-bit operating system, IoWMIDeviceObjectToProviderId will convert the 64-bit device object to a 32-bit provider ID.
