PmReturn_t list_append	(	pPmObj_t	plist,
		pPmObj_t	pobj
	)

Appends the given obj to the end of the given list.

Allocate the memory for the node. Do not copy obj, just reuse ptr.

Parameters:

	plist	Ptr to list
	pobj	Ptr to item to append

Returns:

Return status

PmReturn_t list_clear

(

pPmObj_t

plist

)

Removes all items from the list and zeroes the length.

Parameters:

pobj

List to clear

Returns:

Return status

PmReturn_t list_copy	(	pPmObj_t	pobj,
		pPmObj_t *	r_pobj
	)

Makes a copy of the given list.

Allocate the necessary memory for root and nodes. Duplicate ptrs to objs.

Parameters:

	pobj	Ptr to source list
	r_pobj	Return; Addr of ptr to return obj

Returns:

Return status

PmReturn_t list_delItem	(	pPmObj_t	plist,
		int16_t	index
	)

Removes the item at the given index. Raises a TypeError if the first argument is not a list. Raises an IndexError if the index is out of bounds.

Parameters:

	plist	Ptr to list obj
	index	Index of item to remove

Returns:

Return status

PmReturn_t list_getItem	(	pPmObj_t	plist,
		int16_t	index,
		pPmObj_t *	r_pobj
	)

Gets the object in the list at the index.

Parameters:

	pobj	Ptr to list obj
	index	Index into list
	r_pobj	Return; ptr to return obj

Returns:

Return status

PmReturn_t list_index	(	pPmObj_t	plist,
		pPmObj_t	pitem,
		uint16_t *	r_index
	)

Finds the first index of the item that matches pitem. Returns an ValueError Exception if the item is not found.

Parameters:

	plist	Ptr to list obj
	item	Ptr to object to be removed
	r_index	Addr of the variable for index

Returns:

Return status

PmReturn_t list_insert	(	pPmObj_t	plist,
		int16_t	index,
		pPmObj_t	pobj
	)

Inserts the object into the list at the desired index.

Parameters:

	plist	Ptr to list obj
	pobj	Ptr to obj to insert
	index	Index of where to insert obj

Returns:

Return status

PmReturn_t list_new

(

pPmObj_t *

r_pobj

)

Allocates a new List object.

If there is not enough memory to allocate the List, the return status will indicate an OutOfMemoryError that must be passed up to the interpreter. Otherwise, a ptr to the list is returned by reference and the return status is OK.

Parameters:

r_pobj

Return; addr of ptr to obj

Returns:

Return status

PmReturn_t list_remove	(	pPmObj_t	plist,
		pPmObj_t	item
	)

Removes a given object from the list.

Parameters:

	plist	Ptr to list obj
	item	Ptr to object to be removed

Returns:

Return status

PmReturn_t list_replicate	(	pPmObj_t	psrclist,
		int16_t	n,
		pPmObj_t *	r_pnewlist
	)

Creates a new list with the contents of psrclist copied pint number of times. This implements the python code "[0,...] * N" where the list can be any list and N is an integer.

Parameters:

	psrclist	The source list to replicate
	n	The integer number of times to replicate it
	r_pnewlist	Return; new list with its contents set.

Returns:

Return status

PmReturn_t list_setItem	(	pPmObj_t	plist,
		int16_t	index,
		pPmObj_t	pobj
	)

Sets the item in the list at the index.

Parameters:

	pobj1	Ptr to list
	index	Index int
	pobj2	Ptr to obj

Returns:

Return status
