@deftypefun {unsigned int} {gnutls_dtls_get_mtu} (gnutls_session_t @var{session})

@var{session}: is a @code{gnutls_session_t}  type.

This function will return the MTU size as set with

@code{gnutls_dtls_set_mtu()} . This is not the actual MTU

of data you can transmit. Use @code{gnutls_dtls_get_data_mtu()} 

for that reason.

@strong{Returns:} the set maximum transfer unit.

@strong{Since:} 3.0
