gd_frameoffset64, gd_alter_frameoffset64 ā€” 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.
