MCI_DELETE

Removes data from the MCI element. 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_DELETE:

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 delete operation should finish before MCI returns control to the application.

LPMCI_GENERIC_PARMS lParam2

Specifies a far pointer to an MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)

Waveform Audio Extensions

The following extensions for lParam1 apply to wave audio devices:

MCI_FROM	Specifies that a beginning position is included in the dwFrom member of the structure identified by lParam2. The units assigned to the position values is specified with the MCI_SET_TIME_FORMAT flag of the MCI_SET command.
MCI_TO	Specifies that an ending position is included in the dwTo member of the structure identified by lParam2. The units assigned to the position values is specified with the MCI_SET_TIME_FORMAT flag of the MCI_SET command.

Note that lParam2 specifies a far pointer to an MCI_WAVE_DELETE_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)
