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 one defines GD_64BIT_API or _LARGEFILE64_SOURCE before including getdata.h.

       If  off_t  is  a  64-bit type (possibly because _FILE_OFFSET_BITS has been defined to 64),
       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.
