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 .
