close(unlink_now=false)
public
Closes the file. If unlink_now is true, then the file will be
unlinked (deleted) after closing. Of course, you can choose to later call
#unlink if you do not unlink it now.
If you don’t explicitly unlink the
temporary file, the removal will be delayed until the object is finalized.
