I'm not sure what you mean by "call_dll",
however, it's my impression that you will crash if
you declare the wrong number of arguments to a C routine
that you call from Euphoria, but getting the void or non-void
part of its declaration wrong will not matter.
In the worst case you will just get a garbage value returned,
or you will ignore a legitimate value that is returned.
Maybe someone can test this to be sure.
