** Description: Header file for ASPI for Win32. This header includes
** macro and type declarations, and can be included without
** modification when using Borland C++ or Microsoft Visual
** C++ with 32-bit compilation. If you are using a different
** compiler then you MUST ensure that structures are packed
** onto byte alignments, and that C++ name mangling is turned
** off.

** Notes: This file created using 4 spaces per tab.
