knet_handle_enable_pmtud_Kronosnet Programmeknet_handle_enable_pmtud_notify(3)

NAME
       knet_handle_enable_pmtud_notify	-  install a callback to receive PMTUd
       changes

SYNOPSIS
       #include	<libknet.h>

       int knet_handle_enable_pmtud_notify(
	   knet_handle_t				       knet_h,
	   void						      *pmtud_notify_fn_private_data,
	   void(*)(void	*private_data, unsigned	int data_mtu)  pmtud_notify_fn
       );

DESCRIPTION
       knet_handle_enable_pmtud_notify

       knet_h -	pointer	to knet_handle_t

       pmtud_notify_fn_private_data void pointer to data that can be  used  to
       identify	the callback.

       pmtud_notify_fn	is  a  callback	 function that is invoked every	time a
       path MTU	size change is detected. The function allows libknet to	notify
       the  user  of  data  MTU,  that's the max value that can	be send	onwire
       without fragmentation. The data MTU will	always be lower	than real link
       MTU  because  it	accounts for protocol overhead,	knet packet header and
       (if configured) crypto overhead,	This function MUST NEVER block or  add
       substantial delays.

RETURN VALUE
       knet_handle_enable_pmtud_notify	returns	 0  on success -1 on error and
       errno is	set.
