NAME

       gd_framenum_subset64  —  perform  a  reverse  look-up  on  a monotonic Dirfile field, with
       largefile support.

SYNOPSIS

       #define GD_64BIT_API
       #include <getdata.h>

       double gd_framenum_subset64(DIRFILE *dirfile, const char *field_code, double value,
              gd_off64_t field_start, gd_off64_t field_end);

DESCRIPTION

       This version of gd_framenum_subset(3) uses a 64-bit offset type (gd_off64_t), where one is
       available, regardless of the size of off_t.  It is only  guaranteed  to  be  available  if
       GD_64BIT_API is defined before including getdata.h.

       If  off_t  is  a  64-bit  type,  this  function  will  the  same as gd_framenum_subset(3).
       Otherwise, gd_framenum_subset(3) will be a version of this function which  uses  a  32-bit
       off_t.
