<P>
If a search using <A HREF="../DM/DMPointLocationType.html#DMPointLocationType">DM_POINTLOCATION_NONE</A> fails, the failure is signaled with a negative cell number. On the
other hand, if <A HREF="../DM/DMPointLocationType.html#DMPointLocationType">DM_POINTLOCATION_NEAREST</A> is used, on failure, the (approximate) nearest point in the mesh is
used, replacing the given point in the input vector. <A HREF="../DM/DMPointLocationType.html#DMPointLocationType">DM_POINTLOCATION_REMOVE</A> returns values only for points
which were located.
