When teaching, the questions from the audience provide an important feedback to me - a notion of whether I was successful in passing the information to the audience, and what to improve or explain in a different way. There are, however, rare occasions when the question just makes me think "WTF?".
Yesterday I tried to explain the
semantics. These two functions are not straightforward, and it probably
takes a while to wrap one's mind around them.
But after that, the usage is quite simple:
the target of the non-local jump is firstly initialized using
setjmp(3), and later the jump itself can be made using
longjmp(3). I have written the following code snipplet
to demonstrate it:
During the lecture when I asked whether there were any questions, the question
was: "But is there any framework for those functions?".
I was totally puzzled:
I probably don't know all the meanings of the English word "framework",
but I think it means something like a higher-level abstraction or environment
to wrap the lower-level things in order to make them simpler to use (often at
a cost of freedom of how to do things). But can this fancy
be made even simpler than it is? It would still be necessary to declare
the label somehow (
setjmp(3)) and then jump to it
WTF? What framework?

Today I have read an announcement of the Anonymous Pro font, which should be optimized for text terminals and for the programming environment. As this clearly matches my use case, I have decided to try it.
I was soooo disappointed. I may be too used to the font I use (Lucida Typewriter, the upper part of the image), but I think Anonymous Pro is clearly worse.
Which terminal font do you use? And how does it compare to Anonymous Pro or some other fonts?
