/liststreams

Usage:

Lists tfio streams opened by tfopen(). The tfin, tfout, and tferr streams are not included.

The columns and their meanings are:

HANDLE: The handle returned by tfopen().
MODE: The mode argument given to tfopen().
FLUSH: Whether automatic flushing is enabled. See tfflush().
NAME: The name argument, if any, given to tfopen(). Files of mode "q" do not need a name, but you may wish to give them one anyway so it appears here.

The return value of /liststreams is the number of open streams listed.
