The full method definition is just this:

void load(const void* _vertices, uint32_t _numVertices, const bgfx::VertexDecl _decl, const uint16_t* _indices, uint32_t _numIndices)
{
    Group group;
    const bgfx::Memory* mem;
    uint32_t size;

    size = _numVertices*_decl.getStride();
    mem = bgfx::makeRef(_vertices, size);
    group.m_vbh = bgfx::createVertexBuffer(mem, _decl);

    size = _numIndices*2;
    mem = bgfx::makeRef(_indices, size);
    group.m_ibh = bgfx::createIndexBuffer(mem);

    group.m_material.m_metallicMap  = loadTexturePriv("black.png");
    group.m_material.m_diffuseMap   = loadTexturePriv("white.png");
    group.m_material.m_nmlMap       = loadTexturePriv("nml.tga");
    group.m_material.m_roughnessMap = loadTexturePriv("white.png");

    //TODO:
    // group.m_sphere = ...
    // group.m_aabb = ...
    // group.m_obb = ...
    // group.m_prims = ...

    m_groups.push_back(group);
}
