@deftypefun {int} {gnutls_certificate_verify_peers3} (gnutls_session_t @var{session}, const char * @var{hostname}, unsigned int * @var{status})
@var{session}: is a gnutls session

@var{hostname}: is the expected name of the peer; may be @code{NULL} 

@var{status}: is the output of the verification

This function will verify the peer's certificate and store the
status in the  @code{status} variable as a bitwise or'd gnutls_certificate_status_t
values or zero if the certificate is trusted. Note that value in  @code{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 @code{gnutls_certificate_set_verify_flags()} . See the documentation
of @code{gnutls_certificate_verify_peers2()}  for details in the verification process.

If the  @code{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 @code{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 @code{gnutls_certificate_verify_peers()} .

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

@strong{Since:} 3.1.4
