**
**  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.
