Code: Select all
int fd = open(DEVICE_PATH, O_RDONLY);
if (fd < 0) {
perror("Failed to open device");
return 1;
}
struct input_event ev;
while (1) {
ssize_t bytes = read(fd, &ev, sizeof(struct input_event));
if (bytes < (ssize_t) sizeof(struct input_event)) {
perror("Failed to read input event");
close(fd);
return 1;
}
// 检查是否为按键事件,并且是 TRIGGER_KEY 按键的按下事件
if (ev.type == EV_KEY && ev.code == TRIGGER_KEY && ev.value == 1) {
// 写您的处理代码
}
}
close(fd);
