The following code illustrates how to start recording at the 5 second position in the current device element, and then overwrite existing data by recording for 5 seconds.

 USHORT            usDeviceID;
 MCI_RECORD_PARMS  mrp;

  /* Start recording at the 5 second position in the current device
     element, and record for 5 seconds, overwriting existing data.     */

  /* Assumes time format set to milliseconds                           */

 mrp.hwndCallback = hwndMyWindow;
                  /* Assign hwndCallback the handle to the PM Window   */
 mrp.ulFrom = (ULONG)  5000;                 /* Record from position   */
 mrp.ulTo = (ULONG) 10000;                   /* Record to position     */

 mciSendCommand(usDeviceID,                  /* Device ID              */
                MCI_RECORD,                  /* MCI record message     */
                MCI_NOTIFY | MCI_FROM |
                MCI_TO |MCI_RECORD_OVERWRITE,
                                             /* Flags for this message */
                (ULONG) &mrp,                /* Data structure         */
                0);                          /* No user parm           */
