:orphan: # PetscObject any PETSc object, `PetscViewer`, `Mat`, `Vec`, `KSP` etc ## Synopsis ``` typedef struct _p_PetscObject *PetscObject; ``` ## Notes This is the base class from which all PETSc objects are derived from. In certain situations one can cast an object, for example a `Vec`, to a `PetscObject` with (`PetscObject`)vec ## See Also `PetscObjectDestroy()`, `PetscObjectView()`, `PetscObjectGetName()`, `PetscObjectSetName()`, `PetscObjectReference()`, `PetscObjectDereference()` ## Level beginner ## Location include/petscsystypes.h ## Examples src/dm/dt/dualspace/impls/lagrange/tutorials/ex1.c
