NAME
       gnutls_certificate_verify_peers - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_certificate_verify_peers(gnutls_session_t session,
       gnutls_typed_vdata_st * data, unsigned int elements, unsigned int *
       status);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls session

       gnutls_typed_vdata_st * data
                   an array of typed data

       unsigned int elements
                   the number of data elements

       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.

       The acceptable  data types are GNUTLS_DT_DNS_HOSTNAME,
       GNUTLS_DT_RFC822NAME and GNUTLS_DT_KEY_PURPOSE_OID.  The former two
       accept as data a null-terminated hostname or email address, and the
       latter a null-terminated object identifier (e.g.,
       GNUTLS_KP_TLS_WWW_SERVER).  If a DNS hostname is provided then this
       function will compare the hostname in the certificate against the given.
       If names do not match the GNUTLS_CERT_UNEXPECTED_OWNER status flag will
       be set.  If a key purpose OID is provided and the end-certificate
       contains the extended key usage PKIX extension, it will be required to be
       have the provided key purpose or be marked for any purpose, otherwise
       verification will fail with GNUTLS_CERT_SIGNER_CONSTRAINTS_FAILURE
       status.

RETURNS
       a negative error code on error and GNUTLS_E_SUCCESS (0) when the peer's
       certificate was successfully parsed, irrespective of whether it was
       verified.

SINCE
       3.3.0
