Getting terminal width in C?

Assuming you are on Linux, I think you want to use the ncurses library instead. I am pretty sure the ttysize stuff you have is not in stdlib. source

Internal static variables in C, would you use them?

I wouldn't want the existence of a static variable to force me to put the function into its own file. What if I have a number of similar functions, each with their own static counter, that I wanted to put into one file? There are enough decisions we have to make about where to put things, without needing one more constraint. source

How do we know that a string element in C is uninitialized?

No, there is no way of knowing what value the array has. You can, however, initialize it with a chosen "default" value of your choice and later check against that. source
