This is the signature of the function:

void pango_font_face_list_sizes(PangoFontFace *face, int **sizes, int *n_sizes);

Can I just call it this way:

pango_font_face_list_sizes( (PangoFontFace *) name, sizes, n_size );

Or I will need to call some function to transfer the name to be the type of
"PangoFontFace"? Or I need to pass the "desc" variable to this function?

Yes, so my thinking is correct.
