There's a lot of good stuff in man 3 Xft describing all the methods.
I faced the same issue with fontconfig, it's not documented well, only the functions signature and the type they take. Take a look here for example. So what you end up doing is detective work, matching and testing different functions.

Take note that Xft, fontconfig, and a bunch of other libs where all written by the small cluster of persons, especially Keith Packard. That's why everyone uses the higher level libraries such as pango instead of relying on the lower level ones. Take a look at this.
