Function Documentation

void __stats_ComputeGlobalStats	(	vlc_object_t *	p_obj,
		global_stats_t *	p_stats
	)

counter_t* __stats_CounterCreate	(	vlc_object_t *	p_this,
		int	i_type,
		int	i_compute_type
	)

Create a statistics counter.

Parameters:

	p_this	a VLC object
	i_type	the type of stored data. One of VLC_VAR_STRING, VLC_VAR_INTEGER, VLC_VAR_FLOAT
	i_compute_type	the aggregation type. One of STATS_LAST (always keep the last value), STATS_COUNTER (increment by the passed value), STATS_MAX (keep the maximum passed value), STATS_MIN, or STATS_DERIVATIVE (keep a time derivative of the value)

int __stats_Get	(	vlc_object_t *	p_this,
		counter_t *	p_counter,
		vlc_value_t *	val
	)

Get the aggregated value for a counter.

Parameters:

	p_this	an object
	p_counter	the counter
	val	a pointer to an initialized vlc_value union. It will contain the retrieved value

Returns:

an error code

		unsigned int	i_id
	)

int __stats_Update	(	vlc_object_t *	p_this,
		counter_t *	p_counter,
		vlc_value_t	val,
		vlc_value_t *	val_new
	)

Update a counter element with new values.

Parameters:

	p_this	a VLC object
	p_counter	the counter to update
	val	the vlc_value union containing the new value to aggregate. For more information on how data is aggregated,

__stats_Create

Parameters:

val_new

a pointer that will be filled with new data

static int CounterUpdate	(	vlc_object_t *	p_handler,
		counter_t *	p_counter,
		vlc_value_t	val,

	)			[static]

Update a statistics counter, according to its type If needed, perform a bit of computation (derivative, mostly) This function must be entered with stats handler lock.

Parameters:
