Functions

Note

All functions, expect List_Compare come with an additional "S" at the end for objects of type zCListSort. (Example: List_NodeS .) Unlike most LeGo packages, pointers are used here, not handles!

List_Create

    The number of the list element.

Return value

The function returns the value of the specified list element.

List_Length

Returns the length of the list (number of all elements).

func int List_Length(var int list)
Parameters
  • var int list
    The list to be used.

Return value

The function returns the number of elements in the list.

List_HasLength

Checks if the list has the specified length.

func int List_HasLength(var int list, var int length)

    The list to be used.
  • var int length
    The desired length.

Return value

The function returns a boolean value indicating whether the list has the specified length or not.

List_End

Returns the last list element of the list.

func int List_End(var int list)
Parameters
  • var int list
    The list to be used.

Return value

The function returns a pointer to the last list element.

List_Concat

Concatenates two lists.

func void List_Concat(var int list, var int list2)
Parameters
  • var int list
    The first list.
  • var int list2
    The second list. Its beginning is appended to the end of the first list.

List_Contains

Returns the last list element with a specific value.

func int List_Contains(var int list, var int data)
Parameters
  • var int list
    The list to be used.
  • var int data
    The value to search for.

Return value

The function returns the number of the last list element with the value data.

List_For

Calls a function for each list element, passing a pointer to the list element as a parameter.

func void List_For(var int list, var string function)
Parameters
  • var int list
    The list to be used.
  • var string function
    Name of a function to be called for each list element (void handler(var int node)).

List_ForF

Similar to List_For, but with a function parameter instead of a string.

func void ListForF(var int list, var func function)
Parameters
  • var int list
    The list to be used.
  • var func function
    The function to be called for each list element (void handler(var int node)).

List_ForI

Similar to List_For, but with a function parameter instead of a string.

func void List_ForI(var int list, var int funcID)
Parameters
  • var int list
    The list to be used.
  • var int funcID
    ID of a function to be called for each list element (void handler(var int node)).

List_Delete

Deletes a list element. All subsequent elements shift position.

func void List_Delete(var int list, var int nr)
Parameters
  • var int list
    The list to be used.
  • var int nr
    The number of the list element to be deleted.

List_Destroy

Destroys the entire list.

func void List_Destroy(var int list)
Parameters
  • var int list
    The list to be destroyed.

List_ToArray

Returns a pointer to a memory area containing all values of the list.

func int List_ToArray(var int list)
Parameters
  • var int list
    The list to be used.

Return value

The function returns a memory area containing all the values of the list.

List_MoveDown

Moves the specified list node down by one position in the list.

func void List_MoveDown(var int list, var int node)

List_MoveUp

Moves the specified list node up by one position in the list.

func void List_MoveUp(var int list, var int node)
Parameters
  • var int list
    The list in which the node is located.
  • var int node
    The node to be moved up.

List_InsertSorted

Inserts a value into a sorted list while preserving the sort order.

func void List_InsertSorted(var int list, var int data, var func compare)
Parameters:
  • var int list
    The list to insert the value into.
  • var int data
    The value to be inserted.
  • var func compare
    A comparison function used to determine the sort order.

List_Compare

func int List_Compare(var int data1, var int data2, var func compare)

  • var int data1
    The first integer value.
  • var int data2
    The second integer value.
  • var func compare
    One of comparison functions. Return value

The function returns the return value of specified comparison function.
