NAME

       gnutls_certificate_verify_peers3 - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       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

DESCRIPTION

       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 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().

RETURNS

       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.

SINCE

       3.1.4
