Win 3.1 used to use .ini files, traditionally stored in the windows
system directory. I believe, though I'm not certain, that putting .ini
files in the system directory is no longer allowed under Windows 95
guidelines (the seal of approval business -- it is entirely possible
that this is true but MS violates it in its own products). NT
encourages the use of the Registry database. REGEDIT lets you look at
the registry database.
I sometimes find it useful to poke around on MS's site for info on
things like this. Searching on ".ini files" at
http://www.microsoft.com/Search/ got me some entries including
http://www.microsoft.com/msdn/sdk/platforms/doc/sdk/protech/src/cc5port_23.htm
which points to GetProfileString, whose entry describes how it is
interpreted on different platforms and different registry settings.
NT actually supports the notion of separate users, but I haven't
figured out how this is supposed to be used from a program. The
article
http://www.microsoft.com/kb/articles/q101/5/07.htm
-- apparently there are HOMEDRIVE and HOMEPATH environment variables.
An article I found searching for "temporary",
http://www.microsoft.com/msdn/sdk/platforms/doc/sdk/win32/sys/src/filesio_24.htm
suggests using GetTempPath and GetTempFileName. It might be worth
double checking that these are available under Win32s -- I think they
probably are, but I haven't checked.
