NAME         top

       gnutls_session_set_verify_output_function - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

       void gnutls_session_set_verify_output_function(gnutls_session_t
       session, gnutls_verify_output_function * func);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_x509_trust_list_t type.

       gnutls_verify_output_function * func
                   is the callback function

DESCRIPTION         top

       This function sets a callback to be called when the peer's
       certificate chain has to be verified and full path to the trusted
       root has to be printed.

       The callback's function prototype is defined in `x509.h': int
       (*callback)( gnutls_x509_crt_t cert, gnutls_x509_crt_t issuer,
       gnutls_x509_crl_t crl, unsigned int verification_output);

       If the callback function is provided then gnutls will call it, in
       the certificate verification procedure.  To verify the
       certificate chain and print its path uptp the trusted root,
       functions such as gnutls_certificate_verify_peers(),
       gnutls_x509_trust_list_verify_crt(), and
       gnutls_x509_trust_list_verify_crt2() can be used. The callback is
       set in _gnutls_verify_crt_status() and
