void foo(void)   says 'foo' is a function taking no args and returning no 
value

void (*bar)(void)  equally says '*bar' is a function taking no args and 
returning no value
therefore bar is a pointer to a function taking no args and returning value

Contrariwise,
void *bar(void)  would say 'bar' is a function taking no args and returning 
a void*
which is to say, the parentheses around *bar are controlling precedence.
