NAME top

   udev_enumerate_scan_devices, udev_enumerate_scan_subsystems,
   udev_enumerate_get_list_entry, udev_enumerate_add_syspath,
   udev_enumerate_get_udev - Query or modify a udev enumerate object

SYNOPSIS top

   **#include <libudev.h>**

   **int**
                                   **udev_enumerate_scan_devices(struct udev_enumerate ***_udevenumerate_**);**

   **int**
                                      **udev_enumerate_scan_subsystems(struct udev_enumerate ***_udevenumerate_**);**

   **struct udev_list_entry**
                                                         ***udev_enumerate_get_list_entry(struct udev_enumerate ***_udevenumerate_**);**

   **int**
                                  **udev_enumerate_add_syspath(struct udev_enumerate ***_udevenumerate_**,**
                                  **const char ***_syspath_**);**

   **struct udev**
                                        ***udev_enumerate_get_udev(struct udev_enumerate ***_udevenumerate_**);**

RETURN VALUE top

   On success, **udev_enumerate_scan_devices()**,
   **udev_enumerate_scan_subsystems()** and **udev_enumerate_add_syspath()**
   return an integer greater than, or equal to, **0**.

   On success, **udev_enumerate_get_list_entry()** returns a pointer to
   the first entry in the list of found devices. If the list is
   empty, or on failure, **NULL** is returned.

   **udev_enumerate_get_udev()** always returns a pointer to the udev
   context that this enumerated object is associated with.

HISTORY top

   **udev_enumerate_scan_devices()**, **udev_enumerate_scan_subsystems()**,
   **udev_enumerate_get_list_entry()**, **udev_enumerate_add_syspath()**, and
   **udev_enumerate_get_udev()** were added in version 221.
