  20  * FIXME: Rather non-functional functions for now.
  21  *
  22  * See:
  23  * http://www.geocities.com/SiliconValley/Network/5317/drivers.html
  24  * http://willemer.de/informatik/windows/inf_info.htm (German)
  25  * DDK: setupx.h
  26  * http://mmatrix.tripod.com/customsystemfolder/infsysntaxfull.html
  27  * http://www.rdrop.com/~cary/html/inf_faq.html
  28  *
  29  * Stuff tested with:
  30  * - rs405deu.exe (German Acroread 4.05 setup)
  31  * - ie5setup.exe
  32  * - Netmeeting
  33  *
  34  * FIXME:
  35  * - string handling is... weird ;) (buflen etc.)
  36  * - memory leaks ?
  37  * - separate that mess (but probably only when it's done completely)
  38  *
  39  * SETUPX consists of several parts with the following acronyms/prefixes:
  40  * Di   device installer (devinst.c ?)
  41  * Gen  generic installer (geninst.c ?)
  42  * Ip   .INF parsing (infparse.c)
  43  * LDD  logical device descriptor (ldd.c ?)
  44  * LDID logical device ID
  45  * SU   setup (setup.c ?)
  46  * Tp   text processing (textproc.c ?)
  47  * Vcp  virtual copy module (vcp.c ?)
  48  * ...
  49  *
  50  * The SETUPX DLL is NOT thread-safe. That's why many installers urge you to
  51  * "close all open applications".
  52  * All in all the design of it seems to be a bit weak.
  53  * Not sure whether my implementation of it is better, though ;-)
