Oops! Here a corrected version.

<Function>
FT_Get_Advance
<Description>
Retrieve the advance value of a given glyph outline in an
@FT_Face.
<Input>
face :: The source @FT_Face handle.
gindex :: The glyph index.
load_flags :: A set of bit flags similar to those used when
calling @FT_Load_Glyph.
<Output>
padvance :: The advance value, either in font units if
@FT_LOAD_NO_SCALE is used, or in 16.16 format for
all other load flags.
If @FT_LOAD_VERTICAL_LAYOUT is set, this is the
vertical advance corresponding to a vertical layout.
Otherwise, it is the horizontal advance in a
horizontal layout.
<Return>
FreeType error code. 0 means success.
<Note>
Quick retrieval of advance widths is possible if a glyph is
unhinted (@FT_LOAD_NO_HINTING), or unscaled (@FT_LOAD_NO_SCALE),
or bitmapped, or if light-hinting is used (@FT_RENDER_MODE_LIGHT),
and the font backend supports it. To check these conditions, add
the @FT_ADVANCE_FLAG_FAST_ONLY flag to `load_flags'; in case of
failure `FT_Err_Unimplemented_Feature' is returned.
If the above conditions are met and @FT_LOAD_NO_SCALE isn't set,
a value equal to the `linearHoriAdvance' (or `linearVertAdvance')
field of a @FT_GlyphSlot structure is returned in `padvance'.
If the above conditions aren't met and @FT_LOAD_NO_SCALE isn't
set, @FT_Load_Glyph is called, a value equal to the `advance'
field of a @FT_GlyphSlot structure is returned in `padvance' (but
in 16.16 format).
If the returned advance value gets scaled, the affine
transformation specified by @FT_Set_Transform is not applied.
