Return true (nonzero) if the standard I/O file \var{fp} with name
Returns the ``bitwise exclusive or'' of \var{o1} by \var{o2} on success, or
\NULL{} on failure. The operation is done \emph{in-place} when \var{o1}
supports it. This is the equivalent of the Python expression \samp{\var{o1}
-\^= \var{o2}}.
