Detailed Description

Trickle algorithm library.

Typedef Documentation

net_trickle_cb_t

net_trickle_cb_t

#include <include/net/trickle.h>

Trickle timer callback.

The callback is called after Trickle timeout expires.

Parameters

trickle	The trickle context to use.
do_suppress	Is TX allowed (true) or not (false).
user_data	The user data given in net_trickle_start() call.

Function Documentation

net_trickle_consistency()

void net_trickle_consistency

(

struct net_trickle *

trickle

)

#include <include/net/trickle.h>

To be called by the protocol handler when it hears a consistent network transmission.

Parameters

trickle

Pointer to Trickle struct.

net_trickle_create()

int net_trickle_create	(	struct net_trickle *	trickle,
		uint32_t	Imin,
		uint8_t	Imax,
		uint8_t	k
	)

#include <include/net/trickle.h>

Create a Trickle timer.

Parameters

trickle	Pointer to Trickle struct.
Imin	Imin configuration parameter in ms.
Imax	Max number of doublings.
k	Redundancy constant parameter. See RFC 6206 for details.

Returns

Return 0 if ok and <0 if error.

net_trickle_inconsistency()

void net_trickle_inconsistency

(

struct net_trickle *

trickle

)

#include <include/net/trickle.h>

To be called by the protocol handler when it hears an inconsistent network transmission.

Parameters

net_trickle_is_running()

static bool net_trickle_is_running ( struct net_trickle *  trickle )

inlinestatic

#include <include/net/trickle.h>

Check if the Trickle timer is running or not.

Parameters

trickle

Pointer to Trickle struct.

Returns

int net_trickle_start	(	struct net_trickle *	trickle,
		net_trickle_cb_t	cb,
		void *	user_data
	)

#include <include/net/trickle.h>

Start a Trickle timer.

Parameters

trickle	Pointer to Trickle struct.
cb	User callback to call at time T within the current trickle interval
user_data	User pointer that is passed to callback.

Returns

Return 0 if ok and <0 if error.

net_trickle_stop()

int net_trickle_stop

(

struct net_trickle *

trickle

)

#include <include/net/trickle.h>

Stop a Trickle timer.

Parameters

trickle

Pointer to Trickle struct.

Returns

Return 0 if ok and <0 if error.
