Am I missing something, or why couldn't you use getenv("TMPDIR")?  It is
defined by POSIX:

http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html

If it is not available, falling back to "/tmp" would not be an error as
far as I can tell.  POSIX environments should have TMPDIR defined.
