-# The lookup keys are composed in:

-# Note: The format of the "evdev:" prefix match key is a

-# is not necessarily expected to be a stable ABI.
-#
-# Match string formats:
-# evdev:<modalias>
-# evdev:name:<device name>:dmi:<dmi string>
-#
-# To add local entries, create a new file
-# /etc/udev/hwdb.d/61-evdev-local.hwdb

-# udevadm hwdb --update
-# udevadm trigger /dev/input/eventXX
-# where /dev/input/eventXX is the device in question. If in

-# If your changes are generally applicable, open a bug report on

- <title>Description</title>
-
- <para><function>sd_pid_get_session()</function> may be used to
- determine the login session identifier of a process identified by
- the specified process identifier. The session identifier is a
- short string, suitable for usage in file system paths. Note that
- not all processes are part of a login session (e.g. system service
- processes, user processes that are shared between multiple
- sessions of the same user, or kernel threads). For processes not
- being part of a login session this function will fail with
- -ENXIO. The returned string needs to be freed with the libc
- <citerefentry
- project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- call after use.</para>
-
- <para><function>sd_pid_get_unit()</function> may be used to
- determine the systemd system unit (i.e. system service) identifier
- of a process identified by the specified PID. The unit name is a
- short string, suitable for usage in file system paths. Note that
- not all processes are part of a system unit/service (e.g. user
- processes, or kernel threads). For processes not being part of a
- systemd system unit this function will fail with -ENXIO (More
- specifically: this call will not work for processes that are part
- of user units, use <function>sd_pid_get_user_unit()</function> for
- that.) The returned string needs to be freed with the libc
- <citerefentry
- project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- call after use.</para>
-
- <para><function>sd_pid_get_user_unit()</function> may be used to
- determine the systemd user unit (i.e. user service) identifier of
- a process identified by the specified PID. This is similar to
- <function>sd_pid_get_unit()</function> but applies to user units
- instead of system units.</para>
-
- <para><function>sd_pid_get_owner_uid()</function> may be used to
- determine the Unix user identifier of the owner of the session of
- a process identified the specified PID. Note that this function
- will succeed for user processes which are shared between multiple
- login sessions of the same user, where
- <function>sd_pid_get_session()</function> will fail. For processes
- not being part of a login session and not being a shared process
- of a user this function will fail with -ENXIO.</para>
-
- <para><function>sd_pid_get_machine_name()</function> may be used
- to determine the name of the VM or container is a member of. The
- machine name is a short string, suitable for usage in file system
- paths. The returned string needs to be freed with the libc
- <citerefentry
- project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- call after use. For processes not part of a VM or containers this
- function fails with -ENXIO.</para>
-
- <para><function>sd_pid_get_slice()</function> may be used to
- determine the slice unit the process is a member of. See
- <citerefentry><refentrytitle>systemd.slice</refentrytitle><manvolnum>5</manvolnum></citerefentry>
- for details about slices. The returned string needs to be freed
- with the libc
- <citerefentry project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- call after use.</para>
-
- <para>If the <varname>pid</varname> parameter of any of these
- functions is passed as 0, the operation is executed for the
- calling process.</para>

- <function>sd_peer_get_owner_uid()</function>,
