NAME
       gnutls_certificate_verify_peers2 - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_certificate_verify_peers2(gnutls_session_t session, unsigned
       int * status);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls session

       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().

       This function will take into account the OCSP Certificate Status TLS
       extension, as well as the following X.509 certificate extensions: Name
       Constraints, Key Usage, and Basic Constraints (pathlen).

       To avoid denial of service attacks some default upper limits regarding
       the certificate key size and chain size are set. To override them use
       gnutls_certificate_set_verify_limits().

       Note that you must also check the peer's name in order to check if the
       verified certificate belongs to the actual peer, see
       gnutls_x509_crt_check_hostname(), or use
       gnutls_certificate_verify_peers3().

RETURNS
       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.
