Media Control Interface Messages

Media Control Interface (MCI) messages control MCI devices and obtain information about device configuration and capabilities. Applications use the mciSendCommand function to send MCI command messages to MCI devices. MCI has the following groups of command messages:

System Command Messages

Required Command Messages

Basic Command Messages

Extended Command Messages

MCI also uses a window notification message to inform your application when an MCI command completes. If you want MCI notification, your application must specify a window to handle the notification message.
