** TODO (Remove) : Polymorphism of the file handle
Polymorphism of the ~trexio_t~ type is handled by ensuring that the
corresponding types for all back ends can be safely casted to
~trexio_t~. This is done by making the back-end structs start with
~struct trexio_s~:
#+begin_src c
struct trexio_back_end_s {
trexio_t parent ;
/* add below specific back-end data */

** File opening
~trexio_open~ creates a new TREXIO file or opens the existing one.
