NAME
       gnutls_certificate_verify_peers2 - return the peer's certificate verification status

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 try to verify the peer's certificate and return its status (trusted, invalid etc.).  The value of status should be one
       or more of the gnutls_certificate_status_t enumerated elements bitwise or'd. 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.

       This function uses gnutls_x509_crt_list_verify() with the CAs in the credentials as trusted CAs.

       Note that some commonly used X.509 Certificate Authorities are still using Version 1 certificates.  If you want to accept them, you need to
       call gnutls_certificate_set_verify_flags() with, e.g., GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT parameter.

RETURNS
       a negative error code on error and zero on success.
