** 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.
