[Gmsh] different return types with addRuledFaces function in GModel.cpp and GModelFactory.cpp

[Guowei He]

Hi,

I'm confused, in GModel.cpp:

void GModel::addRuledFaces (std::vector<std::vector<GEdge *> > edges)
{
  if(_factory)
    _factory->addRuledFaces(this, edges);
}

but in GModelFactory.cpp:

std::vector<GFace *> GeoFactory::addRuledFaces(GModel *gm,

std::vector<std::vector<GEdge *> > edges)
{
...

And I tried to call a void version of this function using Gmsh factory and
nothing happens.

What's the correct way of generating a ruled surface using Gmsh as a
library?

Many thanks.
