Is this code helpful? (From the routine sfnt_load_face in
src/sfnt/sfobjs.c):

    face->root.family_name = NULL;
    face->root.style_name  = NULL;
    if ( face->os2.version != 0xFFFFU && face->os2.fsSelection & 256 )
    {
      if ( !ignore_typographic_family )
        GET_NAME( TYPOGRAPHIC_FAMILY, &face->root.family_name );
      if ( !face->root.family_name )
        GET_NAME( FONT_FAMILY, &face->root.family_name );

      if ( !ignore_typographic_subfamily )
        GET_NAME( TYPOGRAPHIC_SUBFAMILY, &face->root.style_name );
      if ( !face->root.style_name )
        GET_NAME( FONT_SUBFAMILY, &face->root.style_name );
    }
    else
    {
      GET_NAME( WWS_FAMILY, &face->root.family_name );
      if ( !face->root.family_name && !ignore_typographic_family )
        GET_NAME( TYPOGRAPHIC_FAMILY, &face->root.family_name );
      if ( !face->root.family_name )
        GET_NAME( FONT_FAMILY, &face->root.family_name );

      GET_NAME( WWS_SUBFAMILY, &face->root.style_name );
      if ( !face->root.style_name && !ignore_typographic_subfamily )
        GET_NAME( TYPOGRAPHIC_SUBFAMILY, &face->root.style_name );
      if ( !face->root.style_name )
        GET_NAME( FONT_SUBFAMILY, &face->root.style_name );
    }
