NAME

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

SYNOPSIS

       #include <systemd/sd-bus.h>

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

DESCRIPTION

       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.

RETURN VALUE

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

   Errors
       Returned errors may indicate the following problems:

       -ECHILD
           The bus connection has been created in a different process.

NOTES

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