Declaration

procedure Sort(Compare: TListSortCompare)
procedure Sort(Compare: TListSortCompare;

 SortingAlgorithm: PSortingAlgorithm)

Description

Sort> sorts the pointers in the list. Two pointers are compared by passing them to the Compare function. The result of this function determines how the pointers will be sorted:

• If the result of this function is negative, the first pointer is assumed to be 'less' than the second and will be moved before the second in the list.
• If the function result is positive, the first pointer is assumed to be 'greater than' the second and will be moved after the second in the list.
• if the function result is zero, the pointers are assumed to be 'equal' and no moving will take place.

The sort is done using a quicksort algorithm.
