+Routine Description:

+
+Arguments:
+
+  StartOfBuffer - Unicode buffer to print the results of the parsing of Format into.
+
+  BufferSize    - Maximum number of characters to put into buffer. Zero means 
+                  no limit.
+
+  FormatString  - Unicode format string see file header for more details.
+
+  Marker        - Vararg list consumed by processing Format.
+
+Returns: 
+
+  Number of characters printed.
