       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

       If the  hostname provided is non-NULL then this function will compare the
       hostname in the certificate against it. The comparison will follow the
       RFC6125 recommendations. 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().

       GNUTLS_E_SUCCESS (0) when the validation is performed, or a negative
       error code otherwise.  A sucessful error code means that the  status
       parameter must be checked to obtain the validation status.
