Re: Patch: new function process-file (call-process with file handlers)

I would guess that process-file has to handle a nil value for INFILE
in exactly the same way that call-process does:

if (nargs >= 2 && ! NILP (args[1]))
    {
      infile = Fexpand_file_name (args[1], current_buffer->directory);
      CHECK_STRING (infile);
    }
  else
    infile = build_string (NULL_DEVICE);

Does anybody know how one can do `build_string (NULL_DEVICE)' portably
from Lisp?

Sincerely,

Luc.
