Many of them. The global directory is often c:\windows\temp or similar.

NO no no. There's no guarantee that c: exists or has enough space.

Look for environment variable TEMP or TMP. I think TEMP always exists, most systems have TMP as well. They both point to the same place on my machines:

Win2k:        D:\DOCUME~1\username\LOCALS~1\Temp
WinNT:        E:\TEMP
Win95:        C:\WINDOWS\TEMP

There's probably a more general solution. Look at FILE *tmpfile(void) and char *tmpnam(char *s) in stdio.h.
