DBT_DEVICEREMOVECOMPLETE

The operating system sends the DBT_DEVICEREMOVECOMPLETE device message when a device has been removed.

To send the DBT_DEVICEREMOVECOMPLETE device message, the operating system sends the WM_DEVICECHANGE message with wParam set to DBT_DEVICEREMOVECOMPLETE and lParam set to the address of a DEV_BROADCAST_HDR structure identifying the device removed.

dwData = (DWORD) lParam;

Parameters

dwData

Address of a DEV_BROADCAST_HDR structure identifying the device removed.

Return Values

Return TRUE.

Remarks

The operating system may send a DBT_DEVICEREMOVECOMPLETE message without sending corresponding DBT_DEVICEQUERYREMOVE and DBT_DEVICEREMOVEPENDING messages. In such cases, the applications and drivers must recover from the loss of the device as best they can.
