close(Stream)

The stream corresponding to Stream is closed.

For  upward  compatibility,  this  predicate  also  accepts  an atom as its
argument.   If  there  is  a  single  open  stream  with  this  atom as its
associated  file  name,  then this stream is closed.  If there is more than
one  stream  with  the same file name, then one is selected arbitrarily and
closed.
