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.
HISTORY
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.
