Destroys all the data in a safe array.
This function is typically used when freeing safe arrays that contain elements with data types other than variants. If objects are stored in the array, Release is called on each object in the array. Safe arrays of variant will have VariantClear Function called on each member and safe arrays of BSTR will have SysFreeString Function called on each element. IRecordInfo::RecordClear Function will be called to release object references and other values of a record without deallocating the record.
