需要在 Linux 系统下禁止截屏键事件,可以考虑使用更底层的方法,比如通过访问 /dev/input/eventX 设备来捕获键盘事件。 要有编译方法

是的,可以使用 /dev/input/eventX 设备来捕获键盘事件,并在内核级别禁止截屏键事件。
以下是基本的编译方法:
1. 创建一个新的 C 文件,比如 block_screenshot.c
2. 在文件中添加以下代码:
```c
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <unistd.h>
#include <linux/input.h>
int main()
{
int fd;
struct input_event ev;
fd = open("/dev/input/event0", O_RDONLY);
if (fd == -1) {
perror("open");
exit(1);
}
while (1) {
if (read(fd, &ev, sizeof(struct input_event)) < 0) {
perror("read");
exit(1);
}
if (ev.type == EV_KEY && ev.code == KEY_PRINT) {
printf("Screenshot key pressed. Ignoring it.\n");
continue;
}
printf("Event type: %u, code: %u, value: %d\n",
ev.type, ev.code, ev.value);
}
close(fd);
return 0;
}
```
3. 编译代码:
```sh
gcc block_screenshot.c -o block_screenshot
```
4. 将编译后的可执行文件设置为 SUID root 权限,以便它能够访问 /dev/input/eventX 设备:
```sh
sudo chown root:root block_screenshot
sudo chmod +s block_screenshot
```
5. 运行程序:
```sh
./block_screenshot
```
现在,当按下截屏键时,程序将忽略该事件并继续运行。请注意,此程序只是一个示例,您可能需要根据实际情况进行修改。
