void gnutls_ia_enable(gnutls_session_t session, int allow_skip_on_resume);
is a gnutls_session_t structure.
non-zero if local party allows to skip the
TLS/IA application phases for a resumed session.
Specify whether we must advertise support for the TLS/IA extension
during the handshake.
At the client side, we always advertise TLS/IA if gnutls_ia_enable
was called before the handshake; at the server side, we also
require that the client has advertised that it wants to run TLS/IA
before including the advertisement, as required by the protocol.
Similarly, at the client side we always advertise that we allow
TLS/IA to be skipped for resumed sessions if allow_skip_on_resume
is non-zero; at the server side, we also require that the session
is indeed resumable and that the client has also advertised that it
allows TLS/IA to be skipped for resumed sessions.
After the TLS handshake, call gnutls_ia_handshake_p() to find out
whether both parties agreed to do a TLS/IA handshake, before
calling gnutls_ia_handshake() or one of the lower level gnutls_ia_*
