       sd_bus_enqueue_for_read - Re-enqueue a bus message on a bus connection, for reading


       #include <systemd/sd-bus.h>

       int sd_bus_enqueue_for_read(sd_bus *bus, sd_bus_message *message);


       sd_bus_enqueue_for_read() may be used to re-enqueue an incoming bus message on the local
       read queue, so that it is processed and dispatched locally again, similar to how an
       incoming message from the peer is processed. Takes a bus connection object and the message
       to enqueue. A reference is taken of the message and the caller's reference thus remains in
       possession of the caller. The message is enqueued at the end of the queue, thus will be
       dispatched after all other already queued messages are dispatched.

       This call is primarily useful for dealing with incoming method calls that may be processed
       only after an additional asynchronous operation completes. One example are PolicyKit
       authorization requests that are determined to be necessary to authorize a newly incoming
       method call: when the PolicyKit response is received the original method call may be
       re-enqueued to process it again, this time with the authorization result known.


       On success, this function return 0 or a positive integer. On failure, it returns a
       negative errno-style error code.

       Returned errors may indicate the following problems:

           The bus connection has been created in a different process.


       These APIs are implemented as a shared library, which can be compiled and linked to with
       the libsystemd pkg-config(1) file.
