NAME

       gnutls_dtls_set_mtu - API function

SYNOPSIS

       #include <gnutls/dtls.h>

       void gnutls_dtls_set_mtu(gnutls_session_t session, unsigned int mtu);

ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t structure.

       unsigned int mtu
		   The maximum transfer unit of the transport

DESCRIPTION

       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 Ethenet device with MTU 1500, the DTLS MTU set with this function would  be  1500  -	40
       (IPV6 header) - 8 (UDP header) = 1452.
