In the meantime (as stated in another post in this thread), I found the
explanation in the ReadFileEx() API documentation:
On Windows 95/98/ME, asynchronous I/O works only with serial and TCP/IP
communication ports. Asynchronous I/O with disk files is permitted only
on Windows NT/2000/XP.
The other post of mine links to an updated version of my library which
emulates asynchronous file I/O with synchronous I/O for Win95/98/ME to
spare the programmer using the feature from getting an I/O error on these
Asynchronous I/O is fun! :)
It's also a useful feature on UNIXes, like AIX and Solaris, and since
a couple of years, also available on GNU/Linux and the like. :)
