Enumeration Type Documentation

gnrc_mac_timeout_type_t

enum gnrc_mac_timeout_type_t

Definitions of GNRC_MAC timeout types.

This structure can be extended to contain more needed timeout types of different MAC protocols. Please guard them by appropriate #ifdef directives when applicable.

Enumerator
GNRC_MAC_TIMEOUT_DISABLED	Timeout is disabled, not in used.

Function Documentation

gnrc_mac_clear_timeout()

void gnrc_mac_clear_timeout	(	gnrc_mac_timeout_t *	mac_timeout,
		gnrc_mac_timeout_type_t	type
	)

mac_timeout

)

Reset all the MAC timeouts.

Parameters

[in,out]

[in]	offset	the timeout offset
[in]	pid	the targeted thread pid

gnrc_mac_timeout_is_expired()

bool gnrc_mac_timeout_is_expired	(	gnrc_mac_timeout_t *	mac_timeout,
		gnrc_mac_timeout_type_t	type
	)

Check whether a MAC timeout of type has expired or not.

Parameters

[in,out]	mac_timeout	gnrc_mac timeout management unit
[in]	type	the MAC timeout type

Returns

true, if the MAC time of type is expired

false, if the MAC time of type is not expired, or not exist

gnrc_mac_timeout_is_running()

static bool gnrc_mac_timeout_is_running ( gnrc_mac_timeout_t *  mac_timeout, gnrc_mac_timeout_type_t  type  )

inlinestatic
