gnutls_dtls_set_data_mtu(3) gnutls gnutls_dtls_set_data_mtu(3)
NAME
gnutls_dtls_set_data_mtu - API function
SYNOPSIS
#include <gnutls/dtls.h>
gnutls_dtls_set_data_mtu(3) 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 negotia-
tion or renegotiation, in order to ensure that the MTU is still suffi-
cient to account for the new protocol overhead.
In most cases you only need to call gnutls_dtls_set_mtu() with the max-
imum MTU of your transport layer.
RETURNS
GNUTLS_E_SUCCESS (0) on success, or a negative error code.
SINCE
3.1
