Data Structures
struct	ctgroup_s
	Represents a group of linked cells that share the same unit number, channel selection bitmask, and output intensity value. More...

Functions
int	CT_init (const struct cr_s *cmap, uint32_t size, struct ctable_s **table)
	Initializes table that maps the raw fseq sequence indexes to a known LOR unit and channel number using the provided channel map. The lookup is cached into the table for faster access. The table is dynamically allocated and must be freed with CT_free.
void	CT_set (struct ctable_s *table, uint32_t index, uint8_t output)
	Sets the output intensity for the cell at the given index. This marks the cell as modified, regardless if the new output intensity is the same as the current value.
void	CT_change (struct ctable_s *table, uint32_t index, uint8_t output)
	Changes the output intensity for the cell at the given index. This only marks the cell as modified if the new output intensity is different from the current value.
int	CT_groupof (struct ctable_s *table, uint32_t at, struct ctgroup_s *group)
	Returns a group of linked cells starting at the given index. The group is identified by the unit number, channel section, and output intensity value. Any cells that have not been modified, or do not match, are excluded from the grouping. Assuming the cell at at is valid and modified, group should always contain at least one cell.
void	CT_free (struct ctable_s *table)
	Frees the table and any held resources.

Detailed Description

Cell table for tracking output states.

Function Documentation

CT_change()

void CT_change	(	struct ctable_s *	table,
		uint32_t	index,
		uint8_t	output )

Changes the output intensity for the cell at the given index. This only marks the cell as modified if the new output intensity is different from the current value.

Parameters

table	table to change the output on
index	index of the cell to change
output	intensity to change to

Here is the caller graph for this function:

CT_free()

void CT_free

(

struct ctable_s *

table

)

Frees the table and any held resources.

Parameters

table

table to free

Here is the caller graph for this function:

CT_groupof()

int CT_groupof	(	struct ctable_s *	table,
		uint32_t	at,
		struct ctgroup_s *	group )

Returns a group of linked cells starting at the given index. The group is identified by the unit number, channel section, and output intensity value. Any cells that have not been modified, or do not match, are excluded from the grouping. Assuming the cell at at is valid and modified, group should always contain at least one cell.

Parameters

table	table to search
at	index to start the group search
group	pointer to store the group

Returns

1 if a group was found, 0 if no group was found

Here is the caller graph for this function:

CT_init()

int CT_init	(	const struct cr_s *	cmap,
		uint32_t	size,
		struct ctable_s **	table )

Initializes table that maps the raw fseq sequence indexes to a known LOR unit and channel number using the provided channel map. The lookup is cached into the table for faster access. The table is dynamically allocated and must be freed with CT_free.

Parameters

cmap	channel map to use for lookup
size	number of indexes to map
table	pointer to store the table

Returns

0 on success, or a negative error code on failure

Here is the caller graph for this function:

CT_set()

void CT_set	(	struct ctable_s *	table,
		uint32_t	index,
		uint8_t	output )

Sets the output intensity for the cell at the given index. This marks the cell as modified, regardless if the new output intensity is the same as the current value.

Parameters

table	table to set the output on
index	index of the cell to set
output	intensity to set
