The MCI_STOP command stops all play and record sequences, unloads all play buffers, and ceases display of video images. CD audio, digital-video, MIDI sequencer, videodisc, VCR, and waveform-audio devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand( MCIDEVICEID wDeviceID, MCI_STOP, DWORD dwFlags, (DWORD) (LPMCI_GENERIC_PARMS) lpStop );
Device identifier of the MCI device that is to receive the command message.
MCI_NOTIFY, MCI_WAIT, or, for digital-video and VCR devices, MCI_TEST. For information about these flags, see The Wait, Notify, and Test Flags.
Pointer to an MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)
Returns zero if successful or an error otherwise.
The difference between the MCI_STOP and MCI_PAUSE commands depends on the device. If possible, MCI_PAUSE suspends device operation but leaves the device ready to resume play immediately.
For the CD audio device, MCI_STOP resets the current track position to zero; in contrast, MCI_PAUSE maintains the current track position, anticipating that the device will resume playing.
