NAME

       gd_frameoffset64, gd_alter_frameoffset64 — report or change the frame offset of fields in a dirfile, with
       largefile support

SYNOPSIS

       #define GD_64BIT_API
       #include <getdata.h>

       gd_off64_t gd_frameoffset(DIRFILE *dirfile, int fragment_index);

       int gd_alter_frameoffset64(DIRFILE *dirfile, gd_off64_t offset, int fragment_index, int move);

DESCRIPTION

       These versions of gd_frameoffset(3) and gd_alter_frameoffset(3) use a 64-bit  offset  type  (gd_off64_t),
       where  one  is  available,  regardless of the size of off_t.  They are only available if GD_64BIT_API has
       been defined before including getdata.h.

       If  off_t  is  a  64-bit  type,  these   functions   will   the   same   as   gd_framenum_subset(3)   and
       gd_alter_frameoffset(3).   Otherwise,  gd_framenum_subset(3) and gd_alter_frameoffset(3) will be versions
       of these function which use a 32-bit off_t.
