#include "petscdmlabel.h"

PetscErrorCode DMRemoveLabel(DM dm, const char name[], DMLabel *label)
Not Collective

Input Parameters

dm - The DM object
name - The label name

Output Parameter

label -The DMLabel, or NULL if the label is absent

Notes

DMRemoveLabel(dm,name,NULL) removes the label from dm and calls DMLabelDestroy() on the label.

DMRemoveLabel(dm,name,&label) removes the label from dm, but it DOES NOT call DMLabelDestroy(). Instead, the label is returned and the user is responsible of calling DMLabelDestroy() at some point.
