Finally, to wait at most until a specified time limit, use
:cpp:func:`s4u::Activity::wait_until() <simgrid::s4u::Activity::wait_until>`.
-Every kind of activity can be asynchronous:
-
- - :ref:`s4u::CommPtr <API_s4u_Comm>` are created with
- :cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>` and

- - :ref:`s4u::ExecPtr <API_s4u_Exec>` are created with
- :cpp:func:`s4u::Host::exec_async() <simgrid::s4u::Host::exec_async>`.
- - In the future, it will become possible to have asynchronous IPC
- such as asynchronous mutex lock requests.

The following example shows how to have several concurrent
communications ongoing. First, you have to declare a vector in which
:language: c++
:start-after: init-begin
:end-before: init-end
- :dedent: 4
+ :dedent: 2
Then, you start all the communications that should occur concurrently with
:cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>`.
Finally, the actor waits for the completion of all of them at once
-with
-:cpp:func:`s4u::Comm::wait_all() <simgrid::s4u::Comm::wait_all>`.
+with :cpp:func:`s4u::Comm::wait_all() <simgrid::s4u::Comm::wait_all>`.
.. literalinclude:: ../../examples/cpp/comm-waitall/s4u-comm-waitall.cpp
