udev_device_get_devnode函数来源于libudev库,这是一个用于访问Linux内核udev设备管理器提供的设备信息的库。 检查项目是否已经正确链接了该库: 从错误信息来看,编译器在链接过程中找不到udev_device_get_devnode函数的定义,这通常意味着项目没有正确链接libudev库。确保在编译命令中使用了-ludev选项来链接libudev库。例...

通过调用 udev_device_new_from_syspath() 函数创建一个 udev_device 对象,然后使用 udev_device_get_devnode() 函数获取设备节点的路径。 2. 设备状态获取:udev 可以获取设备的当前状态,如设备是否已连接、设备是否已启用等。使用 udev_device_get_is_initialized() 和 udev_device_get_is_active() 函数即可...
