Dear Corona688,

I want to use key of Scroll Lk to lock the current screen.
I'm quite new in linux c development. But familiar with windows c, c++ programming.

The context is like this:
I want to migrate the application program of Turbo C in Dos OS to Linux environment.
I think you may be expert in Turbo C program.
One function is to get the status of current screen.(locked or unlocked) and set the current screen to be locked or unlocked.

I don't know how to design this kind of migration. Maybe I should not translate line by line, but use another more sensible method.
Can you give some suggestions on this? Thank you very much!
