(@code{int} and @code{bool}), the name of the C variable is the name
of the Lisp variable with @code{-} replaced by @code{_}. When the
variable has type @code{Lisp_Object}, the convention is to also prefix
the C variable name with @code{V}. i.e.
the C variable name with @code{V}. This is an example:

@code{Vmy_lisp_variable}; to define it, use the @code{DEFSYM} macro.

In Lisp, symbols sometimes need to be quoted. To achieve the same
effect in C, you again use the corresponding constant symbol
@code{Qmy_lisp_variable}. For example, when creating a buffer-local
variable (@pxref{Buffer-Local Variables}) in Lisp you would write:
