ICM_DRAW_RENDERBUFFER

  • Article

The ICM_DRAW_RENDERBUFFER message notifies a rendering driver to draw the frames that have been passed to it. You can send this message explicitly or by using the ICDrawRenderBuffer macro.

ICM_DRAW_RENDERBUFFER 
wParam = 0; 
lParam = 0;

Return Values

This message does not return a value.

Remarks

Use this message with hardware that performs its own asynchronous decompression, timing, and drawing.

This message is typically used to perform a seek operation when the driver must be specifically instructed to display each video frame passed to it rather than playing a sequence of video frames.

Requirements

**  Windows NT/2000/XP:** Included in Windows NT 3.1 and later.
**  Windows 95/98/Me:** Included in Windows 95 and later.
**  Header:** Declared in Vfw.h.
