Quick parameters question

[TpOreilly]

I once learned on here that the point of parameters is so you can pass different values to a function() every time you call it. Because the parameters of functions such as winmain() and wndproc() are not used to do that, are they special parameters?

Is there main purpose to be used to pass different values to a function() every time you call it, but they also have the ability to used in ways which the winmain() function uses them? right?
