Need for prefixing a function with (void)

Question

I recently came across a rather unusual coding convention wherein the call for a function returning \"void\" is prefixed with (void).

e.g.

(void)         


        

Answer 1

acedemically: a "function" always returns something, else it would be a procedure. So the Author of this code wants to say "i know this naming is wrong, but i will no change the name, so i make this disturbance visible"
