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
