gnutls_session_set_verify_output_function(3)                            gnutls

NAME
       gnutls_session_set_verify_output_function - API function

SYNOPSIS
       #include <gnutls/x509.h>

       void gnutls_session_set_verify_output_function(gnutls_session_t
       session, gnutls_verify_output_function * func);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls_x509_trust_list_t type.

       gnutls_verify_output_function * func
                   is the callback function

DESCRIPTION
       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
       _gnutls_pkcs11_verify_crt_status().
