Restore the array of points on the transitive closure of the in-edges or out-edges for this point in the DAG
PetscErrorCode DMPlexRestoreTransitiveClosure(DM dm, PetscInt p, PetscBool useCone, PetscInt *numPoints, PetscInt *points)
|mesh ||- The DMPlex
|p ||- The point, which must lie in the chart set with DMPlexSetChart()
|useCone ||- PETSC_TRUE for in-edges, otherwise use out-edges
|numPoints ||- The number of points in the closure, so points is of size 2*numPoints, zeroed on exit
|points ||- The points and point orientations, interleaved as pairs [p0, o0, p1, o1, ...], zeroed on exit
If not using internal storage (points is not NULL on input), this call is unnecessary
Since it returns an array, this routine is only available in Fortran 90, and you must
include petsc.h90 in your code.
The numPoints argument is not present in the Fortran 90 binding since it is internal to the array.
