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.

See the README.TXT included for instructions to compile and run this sample.
