Macro Definition Documentation

#define LE_SLS_LINK_INIT   (le_sls_Link_t){NULL}

When a link is created, it must be initialized by assigning this macro to the link before it can be used.

#define LE_SLS_LIST_INIT   (le_sls_List_t){NULL}

When a list is created, it must be initialized by assigning this macro to the list before the list can be used.

Function Documentation

void le_sls_AddAfter	(	le_sls_List_t *	listPtr,
		le_sls_Link_t *	currentLinkPtr,
		le_sls_Link_t *	newLinkPtr
	)

Adds a link after currentLinkPtr. Ensure that currentLinkPtr is in the list otherwise the behaviour of this function is undefined.

Parameters

[in]	listPtr	List to add to.
[in]	currentLinkPtr	New link will be inserted after this link.
[in]	newLinkPtr	New link to add.

static bool le_sls_IsEmpty ( const le_sls_List_t *  listPtr )

inlinestatic

Checks if a list is empty.

Returns

true if empty, false if not empty.

Parameters

[in]

listPtr

The list.

bool le_sls_IsInList	(	const le_sls_List_t *	listPtr,
		const le_sls_Link_t *	linkPtr
	)

Checks if a link is in the list.

Returns

true if the link is in the list. false if the link is not in the list.

Parameters

[in]	listPtr	List to check.
[in]	linkPtr	Check if this link is in the list.

bool le_sls_IsListCorrupted

(

const le_sls_List_t *

listPtr

)

Checks if the list is corrupted.

Returns

true if the list is corrupted. false if the list is not corrupted.

Parameters

[in]

listPtr

List to check.

size_t le_sls_NumLinks

(

const le_sls_List_t *

listPtr

)

Returns the number of links in a list.

Returns

Number of links.

Parameters

[in]

listPtr

List to count.

le_sls_Link_t* le_sls_Peek

(

const le_sls_List_t *

listPtr

)

Returns the link at the head of the list without removing it from the list.

Returns

Pointer to the head link if successful. NULL if the list is empty.

Parameters

[in]

listPtr

The list.

le_sls_Link_t* le_sls_PeekNext	(	const le_sls_List_t *	listPtr,
		const le_sls_Link_t *	currentLinkPtr
	)

Returns the link next to currentLinkPtr (i.e., the link beside currentLinkPtr that's closer to the tail) without removing it from the list. Ensure currentLinkPtr is in the list otherwise the behaviour of this function is undefined.

Returns

Pointer to the next link if successful. NULL if there is no link next to the currentLinkPtr (currentLinkPtr is at the tail of the list).

Parameters

[in]	listPtr	List containing currentLinkPtr.
[in]	currentLinkPtr	Get the link that is relative to this link.

le_sls_Link_t* le_sls_Pop

(

le_sls_List_t *

listPtr

)

Removes and returns the link at the head of the list.

Returns

Removed link. NULL if the link is not available because the list is empty.

Parameters

[in]

listPtr

List to remove from.

void le_sls_Queue	(	le_sls_List_t *	listPtr,
		le_sls_Link_t *	newLinkPtr
	)

Adds a link to the tail of the list.

Parameters

[in]	listPtr	List to add to.
[in]	newLinkPtr	New link to add.

le_sls_Link_t* le_sls_RemoveAfter	(	le_sls_List_t *	listPtr,
		le_sls_Link_t *	currentLinkPtr
	)

Removes the link found after currentLinkPtr. The user must ensure that currentLinkPtr is in the list otherwise the behaviour of this function is undefined.

Returns

Pointer to the removed link. NULL if there are no more links in the list after currentLinkPtr.

Parameters

[in]	listPtr	The list to remove from.
[in]	currentLinkPtr	The link after this one will be removed from the list.

void le_sls_Stack	(	le_sls_List_t *	listPtr,
		le_sls_Link_t *	newLinkPtr
	)

Adds a link at the head of the list.

Parameters

[in]	listPtr	List to add to.
[in]	newLinkPtr	New link to add.
