Just look at some users of WIN_SMART. Found these with Google:

Function ataReadSmartValues() in
http://cvs.sourceforge.net/viewcvs.py/smartmontools/sm5/atacmds.c?rev=1.2

Function smart_read_values() in
http://www.linux-ide.org/smart/ide-smart.c

There are other examples, too. Of course, you can only use code out of these if your software is going to be available under GNU GPL ...

Look at the source code of an existing program which uses it, such as those to which Jan-Benedict referred.

Also, within a few clicks of the linux-ide.org URL, I found:

	http://www.linux-ide.org/smart/smartmontools-5.0/

which says:

== REFERENCES ==
If you need help in understanding the output of smartctl, a good place to start is to read Section 8.41 of the AT Attachment with Packet Interface-5 (ATA/ATAPI-5) specification. This documents the S.M.A.R.T. functionality which the smartmontools utilities provide access to. You can find Revision 1 of this document at:
http://www.t13.org/project/d1321r1c.pdf

Future versions of the specifications (ATA/ATAPI-6 and ATA/ATAPI-7) can be obtained from:
http://www.t13.org/#FTP_site
Later revisions (2, 3) of the ATA/ATAPI-5 specification are also available there.

The functioning of S.M.A.R.T. is also described by the SFF-8035i revision 2 specification. This is a publication of the Small Form Factors Committee, and can be obtained from SFF Committee, 14426 Black Walnut Ct., Saratoga, CA 95070, USA.
