how justly setwindowshookex & callnexthookex

i justly setup adult windows hook, nonetheless i confused line msdn says "calling callnexthookex duty method unbroken offshoot way optional, nonetheless rarely recommended; otherwise, applications have hallowed hooks accept offshoot notifications competence act wrongly result. should callnexthookex unless definitely need hinder presentation being seen applications.".

i wish good programming citizen unbroken hook. but, offshoot way looks this:

lresult callback cbtproc(int code, wparam wp, lparam lp)
{
    (code != hcbt_createwnd)
        {
                // i here? it's eventuality i requested i pass on?
        relapse 0;
    }

    // it's formula wish (create window)
        callnexthookex(...);
        ...
}

so, happens offshoot way formula isn't i'm prying in? i unbroken hook?

edit: sure problem hhook returned setwindowshookex, needs upheld callnexthookex function.

update: seems offshoot parameter abandoned nt platforms:
