This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<para><function>sd_bus_message_set_destination()</function> sets the destination service name for the specified bus
|
|
message object. The specified name must be a valid unique or well-known service name.</para>
|
|
|
|
<para><function>sd_bus_message_set_sender()</function> sets the sender service name for the specified bus message
|
|
object. The specified name must be a valid unique or well-known service name. This function is useful only for
|
|
messages to send on direct connections as for connections to bus brokers the broker will fill in the destination
|
|
field anyway, and the sender field set by original sender is ignored.</para>
