gnutls_dtls_set_mtu(3)            gnutls           gnutls_dtls_set_mtu(3)

NAME         top

       gnutls_dtls_set_mtu - API function

SYNOPSIS         top

       #include <gnutls/dtls.h>

       void gnutls_dtls_set_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 transfer unit of the transport

DESCRIPTION         top

       This function will set the maximum transfer unit of the transport
       that DTLS packets are sent over. Note that this should exclude the
       IP (or IPv6) and UDP headers. So for DTLS over IPv6 on an Ethernet
       device with MTU 1500, the DTLS MTU set with this function would be
       1500 - 40 (IPV6 header) - 8 (UDP header) = 1452.
