尝试获取鼠标点击坐标时出错
Errors while trying to get mouse click coordinates
我正在尝试 运行 本主题的代码（第一个答案）：getting mouseclick coordinates with Xlib 但它给了我一些错误。
输出：
$ ./a.out
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 2 (X_ChangeWindowAttributes)
Serial number of failed request: 8
Current serial number in output stream: 8
应该使用：gcc c.cc -lX11
并将一个字符串更改为：XSelectInput(display, root, ButtonReleaseMask);
