Parameter |
Description |
pnTiledThreshold |
Pointer to a variable to be updated with a value that represents the minimum amount of free memory required to allow the allocation of conventional bitmaps. For more information, refer to L_SetMemoryThresholds. |
pnMaxConvSize |
Pointer to a variable to be updated with a value that represents the maximum size for a conventional bitmap. For more information, refer to L_SetMemoryThresholds. |
pnTileSize |
Pointer to a variable to be updated with a value that represents the size of the tile for tiled bitmaps. For more information, refer to L_SetMemoryThresholds. |
pnConvTiles |
Pointer to a variable to be updated with a value that represents the maximum number of tiles that will reside in conventional memory at any time. For more information, refer to L_SetMemoryThresholds. |
pnConvBuffers |
Pointer to a variable to be updated with the number of buffers in conventional memory. For more information, refer to L_SetMemoryThresholds. |
This function will allow you to retrieve the parameters set with L_SetMemoryThresholds. For more information on the various thresholds, refer to L_SetMemoryThresholds.
Pass NULL for any parameter you are not interested in retrieving.
None.
