Command Messages

MCI supports command strings and command messages. This section discusses  how to use MCI command messages. For information about the command-string interface, see Command Strings_1H7DZ.

The command-message interface is designed to be used by applications requiring a C-language interface to control multimedia devices. It uses a message-passing paradigm to communicate with MCI devices. You can send a command by using the mciSendCommand_H60X4 function.
