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	  sta‐
       tus 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 overriden
       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_ver‐
       ify_peers3().

RETURNS
       a negative error code on error and GNUTLS_E_SUCCESS (0) on success.
