list

- the list @obj[in] the object to find

Returns

the index if found, otherwise -1

RaveObjectList_insert()

int RaveObjectList_insert	(	RaveObjectList_t *	list,
		int	index,
		RaveCoreObject *	obj )

Inserts the object at the specified index, if index < 0 or index > size, then this function will add the object to the end of the list.

Parameters

[in]	list	- the list
[in]	index	- the index where to insert the object
[in]	obj	- the object to insert.

Removes the item at the specified position and releases it.

Parameters

[in]	list	- the list
[in]	index	- the index of the requested item

Returns

the object

RaveObjectList_remove()

RaveCoreObject * RaveObjectList_remove	(	RaveObjectList_t *	list,
		int	index )

Removes the item at the specified position and returns it.

Parameters

[in]	list	- the list
[in]	index	- the index of the requested item

list

)

Removes the last item.

Parameters

[in]

list

- the list

Returns

the object or NULL if there are no objects

RaveObjectList_size()

int RaveObjectList_size

(

RaveObjectList_t *

list

)

Returns the number of items in this list.

Parameters

[in]

list

- the list

Returns

the number of items in this list.

RaveObjectList_sort()

void RaveObjectList_sort	(	RaveObjectList_t *	list,
		int(*	sortfun )(const void *, const void *) )

Sorts the list according to the provided sort function.

The sort function should return an integer less than, equal to or greater than zero depending on how the first argument is in relation to the second argument.

Parameters

[in]	list	- the list
[in]	sortfun	- the sorting function.
