unsigned int test_lcbb_free1

(

void

)

Frees the oldest message on the que.

Return values:

	0,if	successful
	-1,if	no message to free

Returns:

The status code of LCBB_free

unsigned int test_lcbb_free_all

(

void

)

Frees the all the messages on the que.

Returns:

The number of messages freed

unsigned int test_lcbb_init	(	int	src_board_id,
		int	dst_board_id
	)

Test suite initialization routine.

Parameters:

	src_board_id	The board id of the host LCB, defaults to 3
	dst_board_id	the board id of the destination LCB, defaults to the src_board_id + the master off (0x20)

unsigned int test_lcbb_mark_time	(	int	stall,
		int	want_title
	)

Tests the LCBB_mark_time function.

Parameters:

	stall	The stall time in 50 nsecs ticks
	want_title	Indicates that the title should/should not be displayed

References _CTX::lcb.

unsigned int test_lcbb_send	(	int	style,
		int	n
	)

Fills a buffer in the specified style for the specified number of items.

Parameters:

	style	The filling style 0 = Incrementing byte fill
	n	The number of items to fill, style dependent
