UDEV_EN..._DEVICES(3) udev_enumerate_scan_devices UDEV_EN..._DEVICES(3)
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
#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);
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.
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.
udev_new(3), udev_device_new_from_syspath(3),
udev_enumerate_new(3), udev_enumerate_add_match_subsystem(3),
