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  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),
       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.
