/**
* \brief Get information about our request for usage of the CID
* extension in the current connection.
*
* \param ssl The SSL context to query.
* \param enabled The address at which to store whether the CID extension
* is requested to be used or not. If the CID is
* requested, `*enabled` is set to
* MBEDTLS_SSL_CID_ENABLED; otherwise, it is set to
* MBEDTLS_SSL_CID_DISABLED.
* \param own_cid The address of the buffer in which to store our own
* CID (if the CID extension is requested). This may be
* \c NULL in case the value of our CID isn't needed. If
* it is not \c NULL, \p own_cid_len must not be \c NULL.
* \param own_cid_len The address at which to store the size of our own CID
* (if the CID extension is requested). This is also the
* number of Bytes in \p own_cid that have been written.
* This may be \c NULL in case the length of our own CID
* isn't needed. If it is \c NULL, \p own_cid must be
* \c NULL, too.
*
*\note If we are requesting an empty CID this function sets
* `*enabled` to #MBEDTLS_SSL_CID_DISABLED (the rationale
* for this is that the resulting outcome is the
* same as if the CID extensions wasn't requested).
*
* \return \c 0 on success.
* \return A negative error code on failure.
