I don't have time to analyze this in detail, but, as Lawrence observed, you *must not* rely on internal implementation details of FreeType. > I understand both are very different version initially we were using > 2.0.9 version and creating the font data for post script(.ps file) > we are using these location to write the data in post script file as > post script has limitation in writing the number of bytes and after > a certain threshold(65519 characters) it adds a new line. In general, FreeType is not suited at all as a library to manipulate PostScript files. Regardless of that, the correct way is to extract the 'loca' table with `FT_Load_Sfnt_Table` and parse the table by yourself. This is rather trivial to do, so it shouldn't be much work – and doing so makes your code future-proof. Werner

No it isn’t.
RE: Need Help!!Getting Different glyph_locations in freetype 2.0.9 and 2.10.0
Hi All, In file ttpload.c there is a function tt_face_load_loca and below line filling those values. if ( FT_FRAME_EXTRACT( table_len, face->glyph_locations ) ). I don't know how to fix this and looking for further information/assistance. Appreciate all the help!!.

Do you have to write PostScript files? How are these being consumed? By a printer? By another graphics app? There may be a way to avoid PostScript.
