The MCI_PAUSE command pauses the current action. CD audio, digital-video, MIDI sequencer, VCR, videodisc, and waveform-audio devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand( MCIDEVICEID wDeviceID, MCI_PAUSE, DWORD dwFlags, (DWORD) (LPMCI_GENERIC_PARMS) lpPause );
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. With the MCICDA, MCISEQ, and MCIPIONR drivers, the MCI_PAUSE command works the same as the MCI_STOP command.
For digital-video devices, the lpPause parameter points to an MCI_DGV_PAUSE_PARMS structure.
