ICDrawStart
The ICDrawStart
macro notifies a rendering driver to start its internal clock for the timing of
drawing frames. You can use this macro or explicitly call the ICM_DRAW_START message.
DWORD ICDrawStart(
|
hic |
|
|
); |
|
Parameters
hic
Handle of a
driver.
Return Values
This macro
does not return a value.
Remarks
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 the ICM_DRAW_BEGIN message.
The ICDrawStart
and ICDrawStop macros do not nest. If your driver receives ICDrawStart
before rendering is stopped with ICDrawStop, it should restart rendering
with new parameters.
