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.

Comments

This function will allow you to retrieve the parameters set with L_SetMemoryThresholds. For more information on the various thresholds, refer to L_SetMemoryThresholds.
