gnutls_dtls_set_data_mtu(3) gnutls gnutls_dtls_set_data_mtu(3)
gnutls_dtls_set_data_mtu - API function
#include <gnutls/dtls.h>
int gnutls_dtls_set_data_mtu(gnutls_session_t session, unsigned
int mtu);
gnutls_session_t session
is a gnutls_session_t type.
unsigned int mtu
The maximum unencrypted transfer unit of the session
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.
GNUTLS_E_SUCCESS (0) on success, or a negative error code.
