MCI_CUE

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.

Returns zero if successful. Otherwise, it returns an MCI error code.

DWORD lParam1

The following flags apply to all devices supporting MCI_CUE:

MCI_NOTIFY	Specifies that MCI should post the MM_MCINOTIFY message when this command completes. The window to receive this message is specified in the dwCallback member of the 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 structure. (Devices with extended command sets might replace this structure with a device-specific structure.)

Waveform Audio Extensions

The following additional flags for lParam1 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.

Note that lParam2 specifies a far pointer to the MCI_GENERIC_PARMS structure.
