The WdfPdoRemoveEjectionRelationsPhysicalDevice method removes a specified device from the list of devices that must be ejected when another specified device is ejected.
void WdfPdoRemoveEjectionRelationsPhysicalDevice( WDFDEVICE Device, PDEVICE_OBJECT PhysicalDevice );
A handle to a framework device object.
A pointer to a caller-supplied DEVICE_OBJECT structure that represents a physical device object (PDO).
A system bug check occurs if the driver supplies an invalid object handle.
The PhysicalDevice parameter points to a PDO of a device that WdfPdoRemoveEjectionRelationsPhysicalDevice removes from the list of devices that must be ejected when the device represented by the Device parameter is ejected.
For more information, see Supporting Ejectable Devices.
The following code example removes the device that the pPhysicalDeviceObject structure represents from the list of devices that are ejected when the device that device specifies is ejected.
PDEVICE_OBJECT pPhysicalDeviceObject; NTSTATUS status; ... status = WdfPdoRemoveEjectionRelationsPhysicalDevice( device, pPhysicalDeviceObject );
