|
| - | 572 | ======== Map background data to the address space of process. ======== |
|
| - | 573 | ====================================================================== |
|
| - | 574 | Parameters: |
|
| - | 575 | * eax = 15 - function number |
|
| - | 576 | * ebx = 6 - subfunction number |
|
| - | 577 | Returned value: |
|
| - | 578 | * eax = pointer to background data, 0 if error |
|
| - | 579 | Remarks: |
|
| - | 580 | * Mapped data are available for read and write. |
|
| - | 581 | * Size of background data is 3*xsize*ysize. The system blocks |
|
| - | 582 | changes of background sizes while process works with mapped data. |
|
| - | 583 | * Color of each pixel is stored as 3-bytes value BBGGRR. |
|
| - | 584 | * Pixels of the background image are written sequentially |
|
| - | 585 | from left to right, from up to down. |
