Simple iteration through a singly linked list

◆ LE_SLS_LINK_INIT

#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.

◆ LE_SLS_LIST_DECL_INIT

#define LE_SLS_LIST_DECL_INIT {NULL}

When a list is created it must be initialized to this macro in the declaration, or have LE_SLS_LIST_INIT assigned to it, before being used

◆ LE_SLS_LIST_INIT

#define LE_SLS_LIST_INIT (le_sls_List_t)LE_SLS_LIST_DECL_INIT

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

Typedef Documentation

◆ le_sls_LessThanFunc_t

typedef bool(* le_sls_LessThanFunc_t) (le_sls_Link_t *a, le_sls_Link_t *b)

This is a comparator function for sorting a list.

This must return true if a goes before b in the list.

Function Documentation

◆ le_sls_AddAfter()

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

Adds a link after currentLinkPtr, or to the beginning of the list if currentLinkPtr is NULL. Ensure that currentLinkPtr is in the list (or NULL) 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.

◆ le_sls_IsEmpty()

LE_DECLARE_INLINE bool le_sls_IsEmpty ( const le_sls_List_t * listPtr )

Checks if a list is empty.

Returns: true if empty, false if not empty.

Parameters

[in] listPtr The list.

◆ le_sls_IsHead()

LE_DECLARE_INLINE bool le_sls_IsHead	(	const le_sls_List_t *	listPtr,
		const le_sls_Link_t *	linkPtr
	)

Checks if a link is at the head of the list (next to be popped).

Returns

true if the link is at the head of the list.
false if not.

Parameters

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

◆ le_sls_IsInList()

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.

◆ le_sls_IsListCorrupted()

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.

◆ le_sls_IsTail()

LE_DECLARE_INLINE bool le_sls_IsTail	(	const le_sls_List_t *	listPtr,
		const le_sls_Link_t *	linkPtr
	)

Checks if a link is at the tail of the list (last to be popped).

Returns

true if the link is at the tail of the list.
false if not.

Parameters

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

◆ le_sls_NumLinks()

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_Peek()

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_PeekNext()

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_PeekTail()

le_sls_Link_t* le_sls_PeekTail ( const le_sls_List_t * listPtr )

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

Returns: A pointer to the tail link if successful. NULL if the list is empty.

Parameters

[in] listPtr The list.

◆ le_sls_Pop()

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.

◆ le_sls_Queue()

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_RemoveAfter()

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.

◆ le_sls_Sort()

void le_sls_Sort	(	le_sls_List_t *	listPtr,
		le_sls_LessThanFunc_t	comparatorPtr
	)

Sort a list in ascending order.

Parameters

[in]	listPtr	List to sort
[in]	comparatorPtr	Comparator function for sorting

◆ le_sls_Stack()

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.
