如何将该程序从conio移植到curses? [英] How do I port this program from conio to curses?

问题描述

我在Windows上编写了这个简单的程序.由于Windows具有conio，因此效果很好.

I wrote this simple program on Windows. Since Windows has conio, it worked just fine.

#include <stdio.h>
#include <conio.h>

int main()
{
    char input;

    for(;;)
    {
        if(kbhit())
        {
            input = getch();
            printf("%c", input);
        }
    }
}    

现在，我想将其移植到Linux，而curses/ncurses似乎是正确的方法.我将如何使用这些库代替conio来完成相同的工作?

Now I want to port it to Linux, and curses/ncurses seems like the right way to do it. How would I accomplish the same using those libraries in place of conio?

推荐答案

#include <stdio.h>
#include <ncurses.h>

int main(int argc, char *argv)
{
    char input;

    initscr(); // entering ncurses mode
    raw();     // CTRL-C and others do not generate signals
    noecho();  // pressed symbols wont be printed to screen
    cbreak();  // disable line buffering
    while (1) {
        erase();
        mvprintw(1,0, "Enter symbol, please");
        input = getch();
        mvprintw(2,0, "You have entered %c", input);
        getch(); // press any key to continue
    }
    endwin(); // leaving ncurses mode    
    return 0;
}

构建程序时，请不要忘记将ncurses lib(-L inccurses)标志链接到gcc

When building your program do not forget to link with ncurses lib (-L lncurses) flag to gcc

gcc -g -o sample sample.c -L lncurses

并且此处，您可以看到linux的kbhit()实现.

And here you can see kbhit() implementation for linux.
