SYNOPSIS
#include <libudev.h>
-
int udev_enumerate_scan_devices(struct udev_enumerate *udev_enumerate);
-
int 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
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.
