Get the field dof numbers, in [0, fdof), which are constrained
Synopsis
#include "petscsection.h"
PetscErrorCode PetscSectionGetFieldConstraintIndices(PetscSection s, PetscInt point, PetscInt field, const PetscInt **indices)
Not Collective
Input Parameters
| s | - The PetscSection
|
| field | - The field number
|
| point | - The point
|
Output Parameter
| indices | - The constrained dofs sorted in ascending order

Notes
The indices array, which is provided by the caller, must have capacity to hold the number of constrained dofs, e.g., as returned by PetscSectionGetConstraintDof().
