construct_data() and OSSL_DECODER_CTX_set_cleanup() respectively.</p>

<p>OSSL_DECODER_export() is a fallback function for constructors that cannot use the data they get directly for diverse reasons. It takes the same decode instance <i>decoder_inst</i> that the constructor got and an object <i>reference</i>, unpacks the object which it refers to, and exports it by creating an <a href="../man3/OSSL_PARAM.html">OSSL_PARAM(3)</a> array that it then passes to <i>export_cb</i>, along with <i>export_arg</i>.</p>
