[Applies to KMDF only]
The WdfPdoRemoveEjectionRelationsPhysicalDevice method removes a specified device from the list of devices that must be ejected when another specified device is ejected.
Syntax
VOID WdfPdoRemoveEjectionRelationsPhysicalDevice( [in] WDFDEVICE Device, [in] PDEVICE_OBJECT PhysicalDevice );
Parameters
- Device [in]
-
A handle to a framework device object.
- PhysicalDevice [in]
-
A pointer to a caller-supplied DEVICE_OBJECT structure that represents a physical device object (PDO).
Return value

Examples
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
);
