1. 获取设备属性列表:使用 udev_device_get_properties_list_entry() 函数获取设备的属性列表,返回一个链表。 2. 遍历属性列表:通过遍历属性列表,可以获取设备的每一个属性。使用 udev_list_entry_foreach() 函数进行遍历,通过 udev_list_entry_get_name() 和 udev_list_entry_get_value() 函数获取属性的名称...
使用udev_list_entry_get_name可以得到一个设备结点的sys路径,基于这个路径使用udev_device_new_from_syspath可以创建一个udev设备的映射,用于获取设备属性。获取设备属性使用udev_device_get_properties_list_entry,返回一个存储了设备所有属性信息的链表,使用udev_list_entry_foreach遍历链表,使用udev_list_entry_get_...
