Registering a class that takes a float*

I want to register this function.

GLAPI void GLAPIENTRY glGetFloatv( GLenum pname, GLfloat *params );

I also have a :

GLfloat* get_raw(boost::shared_ptr<std::vector<GLfloat> > p) {
  return &( (*p)[0] );
}


I know that I can do:

.def( "glGetFloatv", &glGetFloatv)
.def( "get_raw", &get_raw);

However, I don't know what types I need to register so that Luabind
will understand the GLfloat* type

I.e. make the following work:

blah.lua:

glGetFloatv(some_constant, some_vector:get_raw());


Thanks!
