Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

|
|
|
|
<para>
|
|
<function>sd_bus_get_fd()</function> returns the file descriptor used to
|
|
communicate with the message bus. This descriptor can be used with
|
|
<citerefentry
|
|
project='die-net'><refentrytitle>select</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
|
|
<citerefentry
|
|
project='die-net'><refentrytitle>poll</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
|
|
or similar functions to wait for incoming messages.
|
|
</para>
|
|
|
|
<para>
|
|
If the bus was created with the
|
|
<citerefentry><refentrytitle>sd_bus_set_fd</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
function, then the <parameter>input_fd</parameter> used in that call is
|
|
returned.
