LMemoryFile::GetMemoryThresholds

#include "ltwrappr.h"

static L_VOID LMemoryFile::GetMemoryThresholds(pnTiledThreshold, pnMaxConvSize, pnTileSize, pnConvTiles, pnConvBuffers)

Gets the current memory restrictions set using LMemoryFile::SetMemoryThresholds.

Parameters

L_INT * 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 LMemoryFile::SetMemoryThresholds.

L_SSIZE_T * 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 LMemoryFile::SetMemoryThresholds.

L_SSIZE_T * 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 LMemoryFile::SetMemoryThresholds.

L_INT * 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 LMemoryFile::SetMemoryThresholds.

L_INT * pnConvBuffers

Pointer to a variable to be updated with the number of buffers in conventional memory. For more information, refer to LMemoryFile::SetMemoryThresholds.

Returns

None.

Example

This example doubles the maximum size for a conventional bitmap.

L_INT LMemoryFile__GetMemoryThresholdsExample() 
{ 
   L_INT nRet; 
   L_SSIZE_T nMaxConvSize;  
 
   /* Get only the max conventional size value */ 
   LMemoryFile::GetMemoryThresholds (NULL, &nMaxConvSize, NULL, NULL, NULL);  
 
   /* Double the max conventional size value */ 
   nRet = LMemoryFile::SetMemoryThresholds(0, (L_INT) nMaxConvSize * 2, 0, 0, 0, MEM_MAXCONVSIZE); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   return SUCCESS; 
}
