# PetscSpaceRegister

Adds a new PetscSpace implementation

### Synopsis

    #include "petscfe.h"
    PetscErrorCode PetscSpaceRegister(const char sname[], PetscErrorCode (*function)(PetscSpace))

Not Collective

### Input Parameters

| name | - The name of a new user-defined creation routine
| create_func | - The creation routine for the implementation type

### Notes

PetscSpaceRegister() may be called multiple times to add several user-defined types of PetscSpaces. The creation function is called when the type is set to 'name'.

### Sample usage

        PetscSpaceRegister("my_space", MyPetscSpaceCreate);

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

        PetscSpaceCreate(MPI_Comm, PetscSpace *);
        PetscSpaceSetType(PetscSpace, "my_space");

or at runtime via the option

        -petscspace_type my_space
