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().
