       gnutls_session_set_verify_function - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void gnutls_session_set_verify_function(gnutls_session_t session,
       gnutls_certificate_verify_function * func);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_certificate_verify_function * func
                   is the callback function

DESCRIPTION         top

       This function sets a callback to be called when peer's certificate
       has been received in order to verify it on receipt rather than doing
       after the handshake is completed. This overrides any callback set
       using gnutls_certificate_set_verify_function().

       The callback's function prototype is: int

       If the callback function is provided then gnutls will call it, in the
       handshake, just after the certificate message has been received.  To
       verify or obtain the certificate the
       gnutls_certificate_verify_peers2(), gnutls_certificate_type_get(),
       gnutls_certificate_get_peers() functions can be used.

       The callback function should return 0 for the handshake to continue
       or non-zero to terminate.
