### VSD_RESTORE - Remarks

MMPM/2 supports the concept of suspending and resuming the state of a device at any point in time. Unlike other environments, multiple applications can simultaneously have a device open and the Media Device Manager will cooperate with the VSD in order to manage the device. The VSD is responsible for saving and restoring the actual hardware device. For further information, see the OS/2 Multimedia Programming Reference (MCI_ RESTORE).
