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.
