MORE INFORMATION
SAFEARAY implements the following methods (in addition to
the standard application object methods).
SlowSort: Sorts an input safearray of BSTRs and returns the sorted array
and the time required for the sort. The array is passed by reference because it
needs to be modified by the sort. SlowSort uses SafeArrayGetElement and
SafeArrayPutElement to access the array elements.
FastSort: Has the same functionality as SlowSort but uses
SafeArrayAccessData to get a pointer to the array elements. This allows array
elements to be accessed directly instead of using SafeArrayGetElement and
SafeArrayPutElement. This accounts for the speed improvement over
SlowSort.
Average: Finds the average of an input safe array of integers. The array
is not passed by reference.
GetArray: Creates and returns a safe array of BSTRs.
