Other Alias

gd_frameoffset64

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.
