On my Linux box there is neither TEMP/TMP/TMPDIR env var defined.
Usually "/tmp" is a good bet.

Moreover if you machine is used by multiple user
**at the same time** which tends to be the case for some Unix
machine.

You should usually find a TEMP location which is user specific
because if not you may end up with multiple user access the same
"TEMP".

On unix you have tmpnam(3), tmpfile(3) which should gives you
appropriate system-unique temporary name/file.

It doesn't really help for the initial question but I wanted to
notice that once you found TMP folder you may have to build
appropriate uniquely named subfolder in order to avoid
possible multi-user name clash.
