(HAL entry #108)
uint HAL_VideoRender(uint flags, uint op, void *params)
| Entry | |
|---|---|
| flags | GraphicsV 13 flags |
| op | GraphicsV 13 operation |
| params | GraphicsV 13 parameter block |
| Exit | |
|---|---|
| >=0 | Render operation was performed |
| <0 | Render operation was not performed |
Use
This is an internal call for OS use only and should not be used by user software. User software should use GraphicsV instead of interacting with the HAL directly.
This call allows the HAL to implement the functionality of GraphicsV 13. Depending on the return code, the operation may or may not be passed on to other claimants in the vector chain.
