@deffn Command toggle-read-only &optional arg
This command toggles whether the current buffer is read-only. It is
intended for interactive use; do not use it in programs. At any given
point in a program, you should know whether you want the read-only flag
on or off; so you can set @code{buffer-read-only} explicitly to the
proper value, @code{t} or @code{nil}.
If @var{arg} is non-@code{nil}, it should be a raw prefix argument.
@code{toggle-read-only} sets @code{buffer-read-only} to @code{t} if
the numeric value of that prefix argument is positive and to
@code{nil} otherwise. @xref{Prefix Command Arguments}.
