RECT *recp,
u_long *p
)
|
Arguments
| recp |
Pointer to the destination rectangular area in the frame buffer |
| p |
Pointer to the source area in main memory |
Return Value
The slot number of the GPU’s draw/command queue where the command resides
is returned.
Explanation
Data from the source area in main memory pointed to by p is transferred
to the rectangular area of the frame buffer pointed to by recp.
Notes
LoadImage() is a non-blocking function, therefore DrawSync()
must be used to determine the completion of transfer. The transfer is not
affected by clipping or offsetting that may be in effect for the drawing
environment. The transfer area must be located within a drawable area:
(0,0) - (1023,511).
