/**********************************************************************************  Module Name:    wnaspi32.h****  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.********************************************************************************/#ifndef __WNASPI32_H__#define __WNASPI32_H__/* *
