+/**
+ * struct input_keymap_entry - used by EVIOCGKEYCODE/EVIOCSKEYCODE ioctls
+ * @scancode: scancode represented in machine-endian form.
+ * @len: length of the scancode that resides in @scancode buffer.
+ * @index: index in the keymap, may be used instead of scancode
+ * @flags: allows to specify how kernel should handle the request. For
+ * example, setting INPUT_KEYMAP_BY_INDEX flag indicates that kernel
+ * should perform lookup in keymap by @index instead of @scancode
+ * @keycode: key code assigned to this scancode
+ *
+ * The structure is used to retrieve and modify keymap data. Users have
+ * option of performing lookup either by @scancode itself or by @index
+ * in keymap entry. EVIOCGKEYCODE will also return scancode or index
+ * (depending on which element was used to perform lookup).
