NAME

       gd_framenum_subset64 — perform a reverse look-up on a monotonic dirfile field

SYNOPSIS

       #define _LARGEFILE64_SOURCE

       #include <getdata.h>

       double gd_framenum_subset64(DIRFILE *dirfile, const char *field_code, double value,
              off64_t field_start, off64_t field_end);

DESCRIPTION

       This version of gd_framenum_subset(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
       gd_framenum_subset().   Otherwise, gd_framenum_subset() will be a version of this function
       which uses a 32-bit off_t.
