DMPlexVecGetClosure

Get an array of the values on the closure of 'point'

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexVecGetClosure(DM dm, PetscSection section, Vec v, PetscInt point, PetscInt *csize, PetscScalar *values[])

Not collective

Input Parameters

	dm	- The DM
	section	- The section describing the layout in v, or NULL to use the default section
	v	- The local vector
	point	- The sieve point in the DM

Output Parameters

	csize	- The number of values in the closure, or NULL
	values	- The array of values, which is a borrowed array and should not be freed

Fortran Notes

Since it returns an array, this routine is only available in Fortran 90, and you must include petsc.h90 in your code.

The csize argument is not present in the Fortran 90 binding since it is internal to the array.
