       gnutls_certificate_verify_peers3 - API function

       #include <gnutls/gnutls.h>

       int gnutls_certificate_verify_peers3(gnutls_session_t session, const
       char * hostname, unsigned int * status);

       gnutls_session_t session
                   is a gnutls session

       const char * hostname
                   is the expected name of the peer; may be NULL

       unsigned int * status
                   is the output of the verification

       This function will verify the peer's certificate and store the status
       in the  status variable as a bitwise or'd gnutls_certificate_status_t
       values or zero if the certificate is trusted. Note that value in
       status is set only when the return value of this function is success
       (i.e, failure to trust a certificate does not imply a negative return
       value).  The default verification flags used by this function can be
       overridden using gnutls_certificate_set_verify_flags(). See the
       documentation of gnutls_certificate_verify_peers2() for details in the
       verification process.

       If the  hostname provided is non-NULL then this function will compare
       the hostname in the certificate against the given. The comparison will
       be accurate for ascii names; non-ascii names are compared byte-by-byte.
       If names do not match the GNUTLS_CERT_UNEXPECTED_OWNER status flag will
       be set.

       In order to verify the purpose of the end-certificate (by checking the
       extended key usage), use gnutls_certificate_verify_peers().

       a negative error code on error and GNUTLS_E_SUCCESS (0) when the peer's
       certificate was successfully parsed, whether or not it was verified.
