No. The way to declare a variadic function in C and C++ is to use ellipses.  An
empty parameter list in C++ declares a function that takes no parameters, like
the (void) list in ANSI C.  An empty parameter list in C declares a function
which takes a fixed number of arguments, but does not specify that number, or
their types.
