You would declare your function like this if you were to name it MyDataBrowserEditItemCallback:

Boolean MyDataBrowserEditItemCallback (
    ControlRef browser, 
    DataBrowserItemID item, 
    DataBrowserPropertyID property, 
    CFStringRef theString, 
    Rect *maxEditTextRect, 
    RgnHandle invalidRgn
);
