Hey everyone;

So a long time ago i created a little menu in C which allowed me to scroll through my options instead of typing in a character each time. The downfall to my menu was that I created it in windows, using the conio.h library. To my knowledge Linux doesn't have access to this library. The following is kinda what my code did.

CODE
char choice

choice = getch();


if (choice == 'ASCII Character')
{
    move option down
}


what choice = getch() allows me to do is press a key, and without pressing enter, something happened. Is there a similar way to do this on a linux platform, or should i get conio.h? Is there another command that also does the same thing?

Any suggestions would be greatly appreciated.

Thanks in advance;
S0n1C!

You can't use conio.h for Linux consoles.

You'll have to use tput & other screen functions, & just use logic to determine which line the user is currently accessing. At least that's how I've done it.

There's a getch() in ncurses.h. Here's a link. Or you can just create your own getch function:
CODE
#include <termios.h>
#include <unistd.h>

int getch() {
    struct termios oldt, newt;
    int ch;
    tcgetattr(STDIN_FILENO,&oldt);
    newt = oldt;
    newt.c_lflag &= ~(ICANON | ECHO);
    tcsetattr(STDIN_FILENO,TCSANOW,&newt);
    ch = getchar();

    tcsetattr(STDIN_FILENO,TCSANOW,&oldt);
    return ch;
}
Best to use the one in ncurses.h though I think.
