The MCI_LOAD command loads a file. Digital-video and video-overlay devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand( MCIDEVICEID wDeviceID, MCI_LOAD, DWORD dwFlags, (DWORD) (LPMCI_LOAD_PARMS) lpLoad );
Device identifier of the MCI device that is to receive the command message.
MCI_NOTIFY, MCI_WAIT, or, for digital-video devices, MCI_TEST. For information about these flags, see The Wait, Notify, and Test Flags.
Pointer to an MCI_LOAD_PARMS structure. (Devices with additional parameters might replace this structure with a device-specific structure. For digital-video devices, the lpLoad parameter points to an MCI_DGV_LOAD_PARMS structure.)
Returns zero if successful or an error otherwise.
The following additional flag applies to all devices supporting MCI_LOAD:
The lpfilename member of the structure identified by lpLoad contains an address of a buffer containing the filename.
The following additional flag is used with the overlay device type:
The rc member of the structure identified by lpLoad contains a valid display rectangle that identifies the area of the video buffer to update.
For video-overlay devices, the lpLoad parameter points to an MCI_OVLY_LOAD_PARMS structure.
