# PetscHeaderDestroy

Final step in destroying a PetscObject

### Synopsis

    #define PetscHeaderDestroy(h)                         \
      (PetscHeaderDestroy_Private((PetscObject)(*h)) ||   \
       PetscFree((*h)->ops) ||                            \
       PetscFree(*h))

    PETSC_EXTERN PetscErrorCode PetscHeaderDestroy_Private(PetscObject);
    PETSC_EXTERN PetscErrorCode PetscObjectCopyFortranFunctionPointers(PetscObject,PetscObject);
    PETSC_EXTERN PetscErrorCode PetscObjectSetFortranCallback(PetscObject,PetscFortranCallbackType,PetscFortranCallbackId*,void(*)(void),void *ctx);
    PETSC_EXTERN PetscErrorCode PetscObjectGetFortranCallback(PetscObject,PetscFortranCallbackType,PetscFortranCallbackId,void(**)(void),void **ctx);

    PETSC_INTERN PetscErrorCode PetscOptionsFindPair_Private(const char[],const char[],char**,PetscBool*);

    PETSC_EXTERN PetscBool PetscCheckPointer(const void*,PetscDataType);

    /*
        Macros to test if a PETSc object is valid and if pointers are valid
    */
    #if !defined(PETSC_USE_DEBUG)

    #define PetscValidHeaderSpecific(h,ck,arg) do

### Input Parameters

h -the header created with PetscHeaderCreate()

Developer Note: This currently is a CPP macro because it accesses (*h)->ops which is a field in the derived class but not the PetscObject base class
