打印到屏幕从C控制台应用程序改写当前行 [英] print to screen from c console application overwriting current line

问题描述

我要覆盖在C控制台程序来实现输出像Linux shell命令顶当前行。如果可能的话，该方法应windows和linux下工作。

I want to overwrite the current line in a c console program to achieve output like in the linux shell command "top". If possible the method should work under windows and linux.

while (i < 100) {
       i++;
       sprintf(cTmp, "%3d", i);
       puts(cTmp);
       if ((character = mygetch()) == 'q') {
          break;
       }
    }

我想覆盖previous号在每次迭代中，如果可能的样子，如果用户输入的字符不停顿的循环。如果用户presses关键'Q'的循环，应立即停止。

I would like to overwrite the previous number in each iteration and if possible look if the user entered a character without pausing the loop. If the user presses the key 'q' the loop should stop immediately.

mvprintw(row, col, "%s", text);
