Not every do_action call automatically has actions attached to it. Some do, but some are just there so developers can hook into them if they need to.
If you want to know what a function does, then do a search in the files for the functions. While the codex does a good job with the various loops and some other stuff, it’s not so good with functions, and there are a lot of them. Once you have found the function (takes around 3 seconds in my IDE) you know what parameters it takes, where you can hook into and to what hooks it is attached.
Quite easy, really
