The run from which to access glyph positions.
A valid pointer to an array of
CGPoint structures, or
The glyph positions in a run are relative to the origin of the line containing the run. The position array will have a length equal to the value returned by
CTRun. The caller should be prepared for this function to return
NULL even if there are glyphs in the stream. If this function returns
NULL, the caller must allocate its own buffer and call
CTRun to fetch the glyph positions.
