Linux C监听鼠标键盘操作

代码：

//monitor.c
#include <stdio.h>
#include <linux/input.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int main(int argc, char** argv)
{
    int keys_fd;
    char ret[2];
    struct input_event t;

    keys_fd = open(argv[1], O_RDONLY);
    if(keys_fd<=0)
    {
        printf("error\n");
        return -1;
    }
    while(1)
    {
        read(keys_fd, &t, sizeof(struct input_event));
        printf("key %i state %i type %i\n", t.code, t.value, t.type);
    }
    close(keys_fd);
    return 0;
}

编译：gcc -o monitor monitor.c

查看外设：ls -l /dev/input/    # 外设有多个event0到event5，不确定哪个是鼠标哪个是键盘，可以都试试

执行：monitor /dev/input/event2
