I have been learning to use the ncurses library and I have come across getstr(). I was wondering how you would erase the text from getstr() on the terminal after the value has already been stored in a variable? I have tried to find the answer on google but no luck!

基本上我想它，以便当用户presses输入的文本会从屏幕上消失。

Basically I want it so when the user presses enter the text will be removed from the screen.

推荐答案

据我所知，ncurses的有两个功能， gotoxy（）和 getxy（），让您跳到屏幕的每一个位置，并告诉你，你在哪里坐落知道了。

As far as I know, ncurses has two functions, gotoxy() and getxy(), which let you jump to every position of the screen and tell you where you are located right know.

跳转到previous线和呼叫 clrtobot（）的前面删除光标之后的一切。

Jump to the front of the previous line and call clrtobot() to erase everything after the cursor.

编辑：

既然你说，清除整个窗口是一个选项，你可以叫清（）（也ncurses库的一部分）。

Since you said that clearing the entire window is an option, you can just call clear() (also part of the ncurses library).
