PetscSFRegister

Adds an implementation of the PetscSF communication protocol.

#include "petscsf.h"  
PetscErrorCode  PetscSFRegister(const char name[],PetscErrorCode (*create)(PetscSF))

Not collective

	name	- name of a new user-defined implementation
	create	- routine to create method context

PetscSFRegister() may be called multiple times to add several user-defined implementations.

   PetscSFRegister("my_impl",MyImplCreate);

Then, this implementation can be chosen with the procedural interface via

    PetscSFSetType(sf,"my_impl")

or at runtime via the option

    -sf_type my_impl

PetscSF, register
