Hi all,

Does anyone know how you can get a filename if all you've got is the
resource (e.g. returned by fopen())?

The reason I ask is that I'd like to use tmpfile() to create a temporary
file (because then it will be automatically deleted should my script
abruptly terminate.) Once I've written my data to this file, I then
need to pass the filename on to an external command, but I can't see any
way to find out what the temporary file is called.

I've tried using fstat(), but this returns everything except the filename.

Any ideas?

Thanks,
Adam.

You can't, unless you write a wrapper which stores the file name.

It depends on what you mean by "abruptly terminate". When your script
crashes or manually interrupted, the temporary file won't be deleted.

Use tempnam() instead:

You can't. But then the file will be deleted when you fclose() it - and
you should close a file you have open for writing before passing it off
to another program, anyway.

Rather, use tempname() to get a unique name, then open it.
