Function Documentation

void print_error

(

unsigned int

error_type

)

This function allows to print an error message matching a code error.

Parameters:

error_type

code error

Returns:

-

Definition at line 42 of file usei-functions.c.

struct qos_metric_measurement get_qos_metric	(	unsigned int	type,
		char *	macaddr,
		char *	dev_name,
		unsigned int *	code_err
	)			[read]

This function allows to get a QOS Link Metric.

Parameters:

	type	(a number) of the metric
	macaddr	MAC Address of a specified node formatted as follow XX:XX:XX:XX:XX:XX
	dev_name	name of the network interface
	code_err	output a code error if an error occurs.

Returns:

qos_metric_measurement the metric formated in qos_metric_measurement structure

Definition at line 97 of file usei-functions.c.

unsigned int metrics_operation	(	struct qos_metric_measurement	qos_metric_1,
		struct qos_metric_measurement	qos_metric_2,
		struct qos_metric_measurement *	qos_metric_result
	)

This function allows to do an operation between 2 QOS Link Metrics of the same type.

Parameters:

	qos_metric_1
	qos_metric_2
	qos_metric_result	result of the operation

Returns:

int 0 if an error occured (metrics aren't in same type), 1 otherwise

Definition at line 175 of file usei-functions.c.

unsigned int is_relevant_metric	(	struct qos_metric_measurement	qos_metric_new,
		struct qos_metric_measurement	qos_metric_old
	)

This function allows to identify if a new QOS Metric Link is revelant or not.

Parameters:

	qos_metric_new	new QOS Metric Link
	qos_metric_old	old QOS Metric Link

Returns:

-

int 1 if the new QOS Metric Link is revelant, 0 otherwise

Definition at line 253 of file usei-functions.c.
