This MCI command message cues a device so that playback or recording begins with minimum delay. Support of this message by a device is optional. The parameters and flags for this message vary according to the selected device.
DWORD lParam1
The following flags apply to all devices supporting MCI_CUE:

Specifies that MCI should post the MM_MCINOTIFY message when this command completes. The window to receive this message is specified in the dwCallback field of the data structure identified by lParam2.
MCI_WAIT
Specifies that the cue operation should finish before MCI returns control to the application.
LPMCI_GENERIC_PARMS lParam2
Specifies a far pointer to the MCI_GENERIC_PARMS data structure. (Devices with extended command sets might replace this data structure with a device-specific data structure.)
DWORD lParam1
The following additional flags apply to wave audio devices:
MCI_WAVE_INPUT
Specifies that a wave input device should be cued.
MCI_WAVE_OUTPUT
Specifies that a wave output device should be cued. This is the default flag if a flag is not specified.
LPMCI_GENERIC_PARMS lParam2
