Get path for (file/temp)?

[neezer]

If I make a temporary file with (file/temp), how do I get the path to that file?

I think it's considered a feature that one cannot get a path:

    (file/temp)

    Open an anonymous temporary file that is removed on close. Raises 
    an error on failure.

Hmm. I was hoping to use this to create a temporary file, write to it, reference the path when calling an external command using janet-sh, then have that file automatically cleaned up when I closed it. Guess I can't?

I've also wanted automatic clean up but haven't found a nice way to accomplish it.

IIUC, the current implementation uses tmpfile:

    FILE *tmp = tmpfile();

According to tmpfile(3):

  The tmpfile() function opens a unique temporary file in binary
  read/write (w+b) mode.  The file will be automatically deleted when it
  is closed or the program terminates.

It looks to me like it's the underlying standard C library that's being relied on to provide the clean up part as the man page has this bit near the top:

LIBRARY
Standard C library (libc, -lc)
