Adding New MCI Commands

This section applies to your driver only if you need to add new MCI commands or provide extensions to the MCI command set. Do the following to add or extend a command set:

1.Define the new MCI messages you plan to support with your driver.

2.Define new data structures and flags for this command to use with mciSendCommand.

3.Create a command table that MCI will use to translate string commands sent through mciSendString into the command messages and data structures used by your driver.

4.Support the new messages in your driver's DriverProc.

5.Register the new command table with MCI in your driver's DRV_LOAD procedure.
