fixed function to not accept any arguments.

As per Pramod's comment on stack overflow:

In C int foo() and int foo(void) are different functions. int foo()
accepts an arbitrary number of arguments, while int foo(void) accepts 0
arguments. In C++ they mean the same thing. I suggest that you use void
consistently when you mean no arguments.
