# VecTaggerRegister

Adds an implementation of the `VecTagger` communication protocol.

## Synopsis

    #include "petscvec.h"
    PetscErrorCode VecTaggerRegister(const char sname[], PetscErrorCode (*function)(VecTagger))

Not Collective, No Fortran Support

## Input Parameters

- sname - name of a new user-defined implementation

- function - routine to create method context

## Notes

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

## Example Usage

       VecTaggerRegister("my_impl", MyImplCreate);

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

    VecTaggerSetType(tagger, "my_impl")

or at runtime via the option

    -snes_type my_solver
