+ * \brief          Set a connection-specific verification callback (optional).
+ *
+ *                 If set, the provided verify callback is called for each
+ *                 certificate in the peer's CRT chain, including the trusted
+ *                 root. For more information, please see the documentation of
+ *                 \c mbedtls_x509_crt_verify().
+ *
+ * \note           This call is analogous to mbedtls_ssl_conf_verify() but
+ *                 binds the verification callback and context to an SSL context
+ *                 as opposed to an SSL configuration.
+ *                 If mbedtls_ssl_conf_verify() and mbedtls_ssl_set_verify()
+ *                 are both used, mbedtls_ssl_set_verify() takes precedence.
+ *
+ * \param conf     The SSL context to use.
+ * \param f_vrfy   The verification callback to use during CRT verification.
+ * \param p_vrfy   The opaque context to be passed to the callback.
