-* Checks if free disk drive storage space is or will fall below critical
-* level. Static configuration values stored in Central Repository are
-* used to determine a critical level for each drive.
-*
-* Usage example:
-* @code
-* TInt dataSize = 500;
-* if ( SysUtil::DiskSpaceBelowCriticalLevelL( &iFsSession, dataSize, EDriveC ) )
-* {
-* // Can not write the data, there's not enough free space on disk.
-* ...
-* }
-* else
-* {
-* // It's ok to actually write the data.
-* ...
-* }
-* @endcode
-*
-* @since S60 v2.0
-*
-* @param aFs File server session. Must be given if available, e.g. from
-* EIKON environment. If NULL, this method will create a
-* temporary session, which causes the method to consume more
-* time and system resources.
-* @param aBytesToWrite Number of bytes the caller is about to write to
-* disk. If value 0 is given, this method checks
-* if the current disk space is already below critical
-* level.
-* @param aDrive Identifies the disk drive to be checked. Numeric values
-* for identifying disk drives are defined in TDriveNumber
-* enumeration.
-*
-* @see TDriveNumber in f32file.h.
-*
-* @return ETrue if disk space would go below critical level after writing
-* aBytesToWrite more data, EFalse otherwise.
-*
-* @leave Leaves with one of the Symbian error codes if checking the disk
-* space fails, for instance if the drive contains no media or there
-* is not enough free memory to create a temporary connection to
-* file server.
