Can it be a symlink?
Because I'm doing it as part of syscalltrack's test suite, and it needs to be a fixed name so that I'll be able to make rules to match on it. We do support pattern matching, so I could use mkstemp() with a fixed template, but I would like to test our '==' operator, not just '=~'. It can be a symlink, I guess.

This brings up another interesting question: how do I make sure all stray files are cleaned up properly on abnormal program termination? Adding a sighandler for each possible signal is annoying (although doable) - is there a better way? -- Sterday 20 Forelithe 7466 http://vipe.technion.ac.il/~mulix/ http://syscalltrack.sf.net/
