MCI_MONITOR
The MCI_MONITOR
command specifies the presentation source. Digital-video devices recognize this
command.
MCIERROR mciSendCommand(MCIDEVICEID wDeviceID,
MCI_MONITOR,
DWORD dwFlags, (DWORD)
(LPMCI_DGV_MONITOR_PARMS) lpMonitor);
Parameters
wDeviceID
Device
identifier of the MCI device that is to receive the command message.
dwFlags
MCI_NOTIFY,
MCI_WAIT, or MCI_TEST. For information about these flags, see The Wait, Notify,
and Test Flags.
lpMonitor
Address of an
MCI_DGV_MONITOR_PARMS
structure.
Return Values
Returns zero
if successful or an error otherwise.
Remarks
The following
additional flags apply to digital-video devices:
MCI_DGV_MONITOR_METHOD
A constant
indicating the method of monitoring is included in the dwMethod member
of the structure identified by lpMonitor.
When the
MCI_DGV_MONITOR_INPUT flag is used in the dwSource member, this selects
the method of monitoring. Typically, different monitoring methods have
different implications on how the hardware is used. The default monitoring
method is selected by the device.
MCI_DGV_MONITOR_SOURCE
A constant
indicating the monitor source is included in the dwSource member of the
structure identified by lpMonitor.
