get_nframes64 (3) Linux Manual Page
NAME
get_nframes64 — report the size of a dirfile with largefile support
SYNOPSIS
#define _LARGEFILE64_SOURCE
#include <getdata.h>
-
off64_t get_nframes64(DIRFILE *dirfile);
DESCRIPTION
get_nframes(3) uses a 64-bit offset type, even if off_t is a 32-bit type. It is only available if one defines _LARGEFILE64_SOURCE. If off_t is a 64-bit type (i.e. if _FILE_OFFSET_BITS is defined to be 64), this function will be called get_nframes(). Otherwise, get_nframes() will be a version of this function which uses a 32-bit off_t.
