How to intercept clicking on a link using the HTMLayout.dll library?

Question

HTML

Good afternoon!
I study and simultaneously write an application using the HTMLayout.dll library. Actually, the question is in the title, how to intercept clicking on any link in the displayed document using HTMLayout.dll, in order to pull out the href value?
I am writing an application for the desktop, so the href value will contain the path to the program, and after intercepting the click, you need to run the specified program.
I read the documentation, I realized that for each element "a" you need to hang a certain handler, but I still haven't figured out how and what, maybe someone here can help with an example ????
I write on CodeBlocks+Mingw.
