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.
