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 LMemoryFile::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 LMemoryFile::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 LMemoryFile::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 LMemoryFile::SetMemoryThresholds. |
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; }
