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
