- <title>Description</title>
-
- <para><function>sd_event_set_name()</function> can be used to set
- an arbitrary name for the event source
- <parameter>source</parameter>. This name will be used in error
- messages generated by
- <citerefentry><refentrytitle>sd-event</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- for this source. Specified <parameter>name</parameter> must point
- to a <constant>NUL</constant>-terminated string or be
- <constant>NULL</constant>. In the latter case, the name will be
- unset. The string is copied internally, so the
- <parameter>name</parameter> argument is not referenced after the
- function returns.</para>
-
- <para><function>sd_event_set_name()</function> can be used to
- query the current name assigned to source
- <parameter>source</parameter>. It returns a pointer to the current
- name (possibly <constant>NULL</constant>) in
- <parameter>name</parameter>.</para>

- <refsect1>
- <title>Return Value</title>
-
- <para>On success, <function>sd_event_set_name()</function> and
- <function>sd_event_get_name()</function> return a
- non-negative integer. On failure, they return a negative
- errno-style error code.</para>
