NAME         top

       gnutls_dtls_set_data_mtu - API function

SYNOPSIS         top

       #include <gnutls/dtls.h>

       int gnutls_dtls_set_data_mtu(gnutls_session_t session, unsigned
       int mtu);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned int mtu
                   The maximum unencrypted transfer unit of the session

DESCRIPTION         top

       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         top

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