For my terminal library, I put it all in a struct. Then the user 
gets to choose how to initialize it, and its destructor gets a 
chance to cleanup when done. The terminal object also contains 
its methods so you feel like you are getting something out of it 
by using them.

I know you prefer not to have the user call initializer 
functions, but I really do think it is the cleanest way to do it.


Alternatively, you could perhaps have it keep an internal 
is_initialized flag and lazily call init on your other function 
calls if it is not already done. Then if the user wants to 
customize settings, they just call init before calling anything 
else, and if not they skip the init call and it gets default 
setup first time they try to use it.
