ISRegister

Adds a new index set implementation

Synopsis

#include "petscis.h"  
PetscErrorCode  ISRegister(const char sname[], PetscErrorCode (*function)(IS))
Not Collective

Input Parameters

name - The name of a new user-defined creation routine
create_func - The creation routine itself

Notes

ISRegister() may be called multiple times to add several user-defined vectors

Sample usage

    ISRegister("my_is_name",  MyISCreate);

Then, your vector type can be chosen with the procedural interface via

    ISCreate(MPI_Comm, IS *);
    ISSetType(IS,"my_is_name");
or at runtime via the option
    -is_type my_is_name

This is no ISSetFromOptions() and the current implementations do not have a way to dynamically determine type, so dynamic registration of custom IS types will be of limited use to users.
