ICM_DRAW_START

See also ICM_DRAW, ICM_DRAW_BEGIN, ICM_DRAW_END, ICM_DRAW_STOP

wParam = 0;
lParam = 0;

Notifies a rendering driver to start its internal clock for the timing of drawing frames.

• No return value.

This message is used by hardware that performs its own asynchronous decompression, timing, and drawing.

When the driver receives this message, it should start rendering data at the rate specified with ICM_DRAW_BEGIN.

ICM_DRAW_START and ICM_DRAW_STOP do not nest. If your driver receives ICM_DRAW_START before rendering is stopped with ICM_DRAW_STOP, it should restart rendering with new parameters.
