Typedef Documentation

typedef void(* le_timer_ExpiryHandler_t) (le_timer_Ref_t timerRef)

Prototype for timer expiry handler function.

Parameters

timerRef Timer that has expired

typedef struct le_timer* le_timer_Ref_t

Timer object. Created by le_timer_Create().

Function Documentation

le_timer_Ref_t le_timer_Create ( const char * nameStr )

Create the timer object.

Returns: A reference to the timer object.

Parameters

[in] nameStr Name of the timer.

void le_timer_Delete ( le_timer_Ref_t timerRef )

Delete the timer object.

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Delete this timer object

void* le_timer_GetContextPtr ( le_timer_Ref_t timerRef )

Get context pointer for the timer.

This can be used when the timer expires to retrieve data that was previously set.

Returns: Context pointer, which could be NULL if it was not set.

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Get context pointer for this timer object

uint32_t le_timer_GetExpiryCount ( le_timer_Ref_t timerRef )

Get the expiry count of a timer.

The count is returned for currently running and idle timers. The expiry count is reset every time the timer is (re)started.

Returns: Expiry count, or zero if the timer has never expired.

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Get expiry count for this timer object

bool le_timer_IsRunning ( le_timer_Ref_t timerRef )

Is the timer currently running?

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Is this timer object currently running?

void le_timer_Restart ( le_timer_Ref_t timerRef )

Re-start the timer.

Start the given timer. If the timer is currently running, it will be stopped and then started. If the timer is not currently running, it will be started.

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef (Re)start this timer object.

le_result_t le_timer_SetContextPtr	(	le_timer_Ref_t	timerRef,
		void *	contextPtr
	)

Set context pointer for the timer.

This can be used to pass data to the timer when it expires.

Returns

LE_OK on success
LE_BUSY if the timer is currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in]	timerRef	Set context pointer for this timer object
[in]	contextPtr	Context Pointer.

le_result_t le_timer_SetHandler	(	le_timer_Ref_t	timerRef,
		le_timer_ExpiryHandler_t	handlerFunc
	)

Set the timer expiry handler function.

If the handler is NULL, then the previous handler will be removed.

Returns

LE_OK on success
LE_BUSY if the timer is currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in]	timerRef	Set expiry handler for this timer object.
[in]	handlerFunc	Handler function to call on expiry.

le_result_t le_timer_SetInterval	(	le_timer_Ref_t	timerRef,
		le_clk_Time_t	interval
	)

Set the timer interval.

Timer will expire after the interval has elapsed.

Returns

LE_OK on success
LE_BUSY if the timer is currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in]	timerRef	Set interval for this timer object.
[in]	interval	Timer interval.

le_result_t le_timer_SetMsInterval	(	le_timer_Ref_t	timerRef,
		uint32_t	interval
	)

Set the timer interval using milliseconds.

Timer will expire after the interval has elapsed.

Returns

LE_OK on success
LE_BUSY if the timer is currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in]	timerRef	Set interval for this timer object.
[in]	interval	Timer interval in milliseconds.

le_result_t le_timer_SetRepeat	(	le_timer_Ref_t	timerRef,
		uint32_t	repeatCount
	)

Set how many times the timer will repeat.

Timer will repeat the given number of times. A value of 0 means repeat indefinitely. The default is 1, so that a one-shot timer is the default.

Returns

LE_OK on success
LE_BUSY if the timer is currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in]	timerRef	Set repeat count for this timer object
[in]	repeatCount	Number of times the timer will repeat (0 = forever).

le_result_t le_timer_Start ( le_timer_Ref_t timerRef )

Start the timer.

Start the given timer. The timer must not be currently running.

Returns

LE_OK on success
LE_BUSY if the timer is already running

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Start this timer object.

le_result_t le_timer_Stop ( le_timer_Ref_t timerRef )

Stop the timer.

Stop the given timer. The timer must be running.

Returns

LE_OK on success
LE_FAULT if the timer is not currently running

Note: If an invalid timer object is given, the process exits.

Parameters

[in] timerRef Stop this timer object.
