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

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.
