@deftypefun {unsigned int} {gnutls_dtls_get_timeout} (gnutls_session_t @var{session})
@var{session}: is a @code{gnutls_session_t} type.
This function will return the milliseconds remaining
for a retransmission of the previously sent handshake
message. This function is useful when DTLS is used in
non-blocking mode, to estimate when to call @code{gnutls_handshake()}
if no packets have been received.
@strong{Returns:} the remaining time in milliseconds.
@strong{Since:} 3.0
