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>

                                       udev_enumerate_scan_devices(struct udev_enumerate *udev_enumerate);

                                          udev_enumerate_scan_subsystems(struct udev_enumerate *udev_enumerate);

       struct udev_list_entry
                                                             *udev_enumerate_get_list_entry(struct udev_enumerate *udev_enumerate);

       int udev_enumerate_add_syspath(struct udev_enumerate *udev_enumerate,
                                      const char *syspath);

       struct udev
                                            *udev_enumerate_get_udev(struct udev_enumerate *udev_enumerate);

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.
