<p>
Functions defined in this section are all local: they should not be
exposed in the API. To identify them, we append <code>_X</code> to
their name.
</p>
<p>
Users are not able to call directly these functions, so by
construction the context can't be <code>NULL</code>, hence we can check this
with an <code>assert</code> statement.
</p>
<p>
In the functions defined in this section, we use as local variables
</p>
<ul class="org-ul">
<li><code>rc</code>: the return code for QMCkl functions</li>
<li><code>rcio</code>: the return code for TREXIO functions.</li>

<h3 id="org550126b"><span class="section-number-3">1.1</span> Open file</h3>
<div class="outline-text-3" id="text-1-1">
<p>
We first define a helper function to open a file by first trying to
use the TEXT back end, and then the HDF5 back end. If both
strategies fail, a <code>NULL</code> pointer is returned. This will allow to
open only once the file and call multiple small functions to read
groups of data by passing the <code>trexio_t</code> handle.
