The ICDrawStartPlay macro provides the start and end times of a play operation to a rendering driver. You can use this macro or explicitly call the ICM_DRAW_START_PLAYV0VZOJ message.

ICDrawStartPlay(

Parameters

lFrom

Start time.

lTo

End time.

Return Values

This macro does not return a value.

Remarks

This message precedes any frame data sent to the rendering driver.

Units for lFrom and lTo are specified with the ICM_DRAW_BEGIN33JT_2P message. For video data this is normally a frame number. For more information about the playback rate, see the dwRate and dwScale members of the ICDRAWBEGIN_KPKDS structure.

If the end time is less than the start time, the playback direction is reversed.
