Requires both MEMP_STATS and LWIP_STATS_DISPLAY to be defined as 1 in lwipopts.h

Parameters

log_level

The logging level to use.

void coap_lwip_set_input_wait_handler	(	coap_context_t *	context,
		coap_lwip_input_wait_handler_t	handler,
		void *	input_arg
	)

Set up a wait / timeout callback handler for use when the application calls coap_io_process().

Parameters
