LibCSS does not provide this kind of API. Its parser is to be considered
a black box by the outside world. The existing example demonstrates
using LibCSS to parse a stylesheet and then apply the resultant style
information to a document tree. What is unclear about it?

Maybe I am getting the example wrong. So you begin by giving creating a selector context with the node to be search as the selector ( h1 to h7 ) in the example. At this point the parse tree would have already been created. The function css_select_style() stores the result of the search in a css_select_results * . Now I am unable to understand why we pass a  handler struct which contains various function pointers. When will those functions get called ?
