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. |

Example
/* This example doubles the maximum size for a conventional bitmap */
L_INT nMaxConvSize;
/* Get only the max conventional size value */
L_GetMemoryThresholds (NULL, &nMaxConvSize, NULL, NULL, NULL);
/* Double the max conventional size value */
L_SetMemoryThresholds (0, nMaxConvSize * 2, 0, 0, 0, MEM_MAXCONVSIZE);
