exposed in the API. To identify them, we append ~_X~ to
their name.
Users are not able to call directly these functions, so by
construction the context can't be ~NULL~, hence we can check this
with an ~assert~ statement.
In the functions defined in this section, we use as local variables
- ~rc~: the return code for QMCkl functions
- ~rcio~: the return code for TREXIO functions.
