<entry><p>Purpose: </p> </entry>
<entry><p>This constant defines an <i>adjustment</i> to the minimum value
of the size of a heap cell created by Symbian's default heap implementation, <xref href="GUID-EFAFDD75-7E59-306A-882D-317F5564979E.dita"><apiname>RHeap</apiname></xref>.
The calculated minimum value is stored in the protected data member <xref href="GUID-EFAFDD75-7E59-306A-882D-317F5564979E.dita#GUID-EFAFDD75-7E59-306A-882D-317F5564979E/GUID-EEE6E931-D66B-3FF0-B035-73103CFD70A4"><apiname>RHeap::iMinCell()</apiname></xref>. </p> <p>By
changing the value of this constant, the actual minimum size of a heap cell
can be increased. </p> <p>The value of this constant provided by Symbian is
zero, which means that, by default, the minimum heap cell size is the same
as for previous versions of the platform. </p> </entry>
