Yes Valdis is absolutely right about being clear as to what you want to do
and why you would be doing that. Also for what does the api do you need to
understand the code and browse using tools(cscope ctags maybe others) to
check for other APIs doing the same and you would definitely find one for
your need.

The way I would suggest is don't rush through, enjoy the process and not
the result.

Enjoy life,
Rohan
