well i solved it using tmpname(NULL,NULL)... it considers the
temporary directory of the system.
when i use tmpnam() on windows on a non-writable root, the filename
generated (\something) is not writable...
i guess it's an implementation bug
FYI, tmpnam is considered a very bad function to use. If two processes
or threads use it at the same time, it can generate a duplicate
filename. It is much better to use tmpfile() which returns a FILE*
directly, so it can be atomic and avoid duplicate names. It works on
both win32 and Linux, and I assume on most other Unices (including Mac
OSX). That might be a better function to wrap. It has the added
benefit of deleting the file automatically when you close it!
