What is the best way to detect in a C program that arrow key is pressed under Linux or Solaris?
As I know there is no standard C function that can do it. I don't want to use int86 function. I need to do it in a portable way.
Edit: I am asking about console applications.
回答1:
You should look at the curses/ncurses library which will give you advanced screen and keyboard handling for console applications.
There is a lot of documentation available for curses, which is an extensive library.
There is a write-up on this very question available here
回答2:
I believe your program should switch into non-canonical mode to be able to read special characters
回答3:
If you wanted to do this without using something like SDL, you should look into the select() statement and how to use it to read from console input.
