.PP
On success,
\fBudev_enumerate_scan_devices()\fR,
\fBudev_enumerate_scan_subsystems()\fR
and
\fBudev_enumerate_add_syspath()\fR
return an integer greater than, or equal to,
\fB0\fR\&.
.PP
On success,
\fBudev_enumerate_get_list_entry()\fR
returns a pointer to the first entry in the list of found devices\&. If the list is empty, or on failure,
\fBNULL\fR
is returned\&.
.PP
\fBudev_enumerate_get_udev()\fR
always returns a pointer to the udev context that this enumerated object is associated with\&.
