I assume that you are talking about a TrueType font, and you want to
access `vertTypoAscender' and `vertTypoDescender' in the `vhea' table,
right?
To get a pointer to the vertical header data, use
TT_VertHeader* vert_header =
(TT_VertHeader*)FT_Get_Sfnt_Table(face, ft_sfnt_vhea);
I've just added an example to the documentation of the
`FT_Get_Sfnt_Table' function.
