<H3><FONT COLOR="#CC3333">Output Parameter</FONT></H3>
<DT><B>coneOrientation </B> -An array of orientations which are on the in-edges for point p. An orientation is an
integer giving the prescription for cone traversal. If it is negative, the cone is
traversed in the opposite direction. Its value 'o', or if negative '-(o+1)', gives
the index of the cone point on which to start.

<P>
<P>
<H3><FONT COLOR="#CC3333">Fortran Notes</FONT></H3>
Since it returns an array, this routine is only available in Fortran 90, and you must
include petsc.h90 in your code.
<P>
You must also call DMPlexRestoreConeOrientation() after you finish using the returned array.
