mci-device-id

Arguments: mci-device

Returns the id of device. If mci-device-id returns 0, this indicates that the device is closed. This will be the case if the device has never been opened with mci-open, if it has more recently been closed with mci-close, or if the most recent call to mci-open resulted in an error. Otherwise mci-device-id will return a positive integer that is unique for the particular mci-device class, and which is of no use to the application other than the fact that it is positive to indicate that the device is open.

See cg-mci.htm for information about MCI support in Common Graphics.
