linux程序引用X11库,Linux / X11输入库无需创建窗口

好吧,如果你在X11之下并想要获得kbd,你需要抓住它.

如果你不是,我唯一的好答案是来自终端的ncurses.

以下是您从键盘获取所有内容并再次发布的方法：

/* Demo code, needs more error checking, compile

* with "gcc nameofthisfile.c -lX11".

/* weird formatting for markdown follows. argh! */

#include< X11 / Xlib.h>

int main(int argc, char **argv)

{

Display *dpy;

XEvent ev;

char *s;

unsigned int kc;

int quit = 0;

if (NULL==(dpy=XOpenDisplay(NULL))) {

perror(argv[0]);

exit(1);

}

/*

* You might want to warp the pointer to somewhere that you know

* is not associated with anything that will drain events.

* (void)XWarpPointer(dpy, None, DefaultRootWindow(dpy), 0, 0, 0, 0, x, y);

*/

XGrabKeyboard(dpy, DefaultRootWindow(dpy),
