Function Documentation

crinitElosLog()

int crinitElosLog	(	crinitElosSeverityE_t	severity,
		crinitElosEventMessageCodeE_t	messageCode,
		uint64_t	classification,
		const char *	format,
			...
	)

Log a crinit event to elos.

Parameters

severity	The event severity.
messageCode	The event message code.
classification	The event classification bitmask.
format	Format string to format remaining arguments.

Returns

Returns 0 on success, -1 otherwise.

crinitEloslogActivate()

int crinitEloslogActivate

(

bool

e

)

Specify if events should be sent to Elos.

By default, Crinit will not connect to elos. If this is set to true, however, Crinit will connect and send events to the elos daemon.

Parameters

e	true if elos should be used, false otherwise.

Returns

Returns 0 on success, -1 otherwise.

crinitEloslogEventTransmitter()

static void * crinitEloslogEventTransmitter ( void *  arg )

static

crinitEloslogInit()

int crinitEloslogInit

(

void

)

Initialize all components needed to handle event logging.

crinitFetchHWId()

static int crinitFetchHWId ( char *  hwId )

inlinestatic

crinitPublishEvent()

static int crinitPublishEvent ( void const *  element, void const *  data  )
