NAME

       gnutls_dtls_set_data_mtu - API function

SYNOPSIS

       #include <gnutls/dtls.h>

       int gnutls_dtls_set_data_mtu(gnutls_session_t session, unsigned int mtu);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned int mtu
                   The maximum unencrypted transfer unit of the session

DESCRIPTION

       This  function  will  set the maximum size of the *unencrypted* records which will be sent
       over a DTLS session. It is equivalent to calculating the DTLS  packet  overhead  with  the
       current  encryption  parameters,  and  calling  gnutls_dtls_set_mtu()  with that value. In
       particular, this means that you may need to call this function again after any negotiation
       or  renegotiation,  in order to ensure that the MTU is still sufficient to account for the
       new protocol overhead.

       In most cases you only need to call gnutls_dtls_set_mtu() with the  maximum  MTU  of  your
       transport layer.

RETURNS

       GNUTLS_E_SUCCESS (0) on success, or a negative error code.

SINCE

       3.1
