Device
Types
MCI
recognizes a basic set of device types. A device type is a set of MCI
drivers that share a common command set and are used to control similar
multimedia devices or data files. Many MCI commands, such as open (MCI_OPEN), require you to specify a
device type.
The following
table lists the defined device types. The current implementation of MCI
includes command sets for a subset of these devices.
