+  <libsummary>Linked-in drivers in Enea OSE</libsummary>
+  <description>
+    <p>Writing Linked-in drivers that also work on Enea OSE is very similar for
+    how you would do it for Unix. The difference from Unix is that
+    driver_select, ready_input and ready_output all work with signals
+    instead of file descriptors. This means that the driver_select is
+    used to specify which type of signal should trigger calls to
+    ready_input/ready_output. The functions described below are available
+    to driver programmers on Enea OSE to facilitate this.

+    <title>Starting Erlang/OTP</title>
+    <p>
+      Starting Erlang/OTP on OSE is not as simple as on Unix/Windows (yet).
+      First of all you have to explicitly use the beam (or beam.smp) executables
+      found in erts-X.Y.Z/bin as the load module that you run. This in turn
+      means that you have to supply the raw beam arguments to the emulator
+      when starting. Fortunately <c>erl</c> on Unix/Windows has a
+      undocumented flag called <c>-emu_args_exit</c> that can be used to
+      figure out what the arguments to beam look like. For example:</p>
+      <code># erl +Mut false +A 10 +S 4:4 +Muycs256 +P 2096 +Q 2096 -emu_args_exit
+-Mut
+false
+-A
+10
+-S
+4:4
+-Muycs256
+-P
+2096
+-Q
+2096
+--
+-root
+/usr/local/lib/erlang
+-progname
+erl
+--
+-home
+/home/erlang
+--</code>
+    <p>
+      The arguments are printed on seperate lines to make it possible to know
+      what has to be quoted with &quot;. Each line is one quotable unit.
+      So taking the arguments above you can supply them to pm_create or
+      just execute directly on the command line. For example:</p>
+      <code>rtose@acp3400> pm_install erlang /mst/erlang/erts-6.0/bin/beam.smp
+rtose@acp3400> pm_create -c ARGV="-Mut false -A 10 -S 4:4 -Muycs256 -P 2096 -Q 2099 -- -root /mst/erlang -progname erl -- -home /mst/erlang --" erlang
+pid: 0x110059
+rtose@acp3400> pm_start 0x110059</code>
+    <p>
+      Also note that since we are running erl to figure out the arguments on a
+      seperate machine the paths have to be updated. In the example above
+      <c>/usr/local/lib/erlang</c> was replaced by <c>/mst/erlang/</c>. The
+      goal is to in future releases not have to do the special argument handling
+      but for now (17.0-rc2) you have to do it.
+    </p>
+    <note>
+      Because of a limitation in the way the OSE handles stdio when starting
+      load modules using pm_install/create the Erlang shell only reads every
+      other command from stdin. However if you start Erlang using run_erl
+      you do not have this problem. So it is highly recommended that you
+      start Erlang using run_erl.
+    </note>
+  </section>
+
+  <section>
+    <title>run_erl and to_erl</title>
+    <p>
+      In OSE run_erl and to_erl are combined into a single load module called
+      run_erl_lm. Installing and starting the load module will add two new
+      shell commands called run_erl and to_erl. They work in exactly the same
+      way as the unix variants of run_erl and to_erl, except that the read
+      and write pipes have to be placed under the /pipe vm. One additional
+      option also exists to run_erl on ose:
+      <taglist>
+	<tag><c>-block Name</c></tag>
+	<item>The name of the install handle and block that will be created/used by
+	installing and exectuting the first part of the command. If nothing
+	if given the basename of the load module will be used for this value.
+	Example:
+	<code>pm_install erlang /path/to/erlang/vm/beam.smp
+run_erl -daemon -block erlang /pipe/ /mst/erlang_logs/ "beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"</code>
+	</item>
+      </taglist>
+      The same argument munching as when starting Erlang/OTP without run_erl
+      has to be done. If <c>-daemon</c> is given then all error printouts
+      are sent to the ramlog.
+      See also

+    <title>Introduction</title>
+    <p>The main way which programs on Enea OSE interact is through the
+    usage of message passing, much the same way as Erlang processes
+    communicate. There are two ways in which an Erlang programmer can
+    interact with the signals sent from other Enea OSE processes; either
+    through the provided <c>ose</c> module, or by writing a custom linked-in
+    driver. This User's Guide describes and provides examples for both
+    approaches.

+    <p>Erlang/OTP on OSE provides a erlang module called
+    <seealso marker="ose:ose">ose</seealso> that can be used to interact
+    with other OSE processes using message passing. The api in the module
+    is very similar to the native OSE api, so for details of how the
+    functions work please refer to the official OSE documenation. Below
+    is an example usage of the API.

+    <title>Signals in a Linked-in driver</title>
+    <p>
+      Writing Linked-in drivers for OSE is very similar to how it is done
+      for Unix/Windows. It is only the way in which the driver subscribes
+      and consumed external events that is different. In Unix (and Windows)
+      file descriptiors (and Event Objects) are used to select on. On OSE
+      we use signals to deliver the same functionality. There are two large
+      differences between a signal and an fd.
+    </p>
+    <p>
+      In OSE it is not possible for a signal number to be a unique identifier
+      for a resource in the same way as an fd is. For example; let's say we
+      implement a driver that does an asynchronous hunt that uses signal
+      number 1234 as the hunt_sig. If we want to be able to have multiple
+      hunt ports running at the same time we have to have someway of routing
+      the signal to the correct port. This is achieved by supplying a secondary
+      id that can be retrieved through the meta-data or payload of the signal,
+      e.g:
+      <code>ErlDrvEvent event = erl_drv_ose_event_alloc(1234,port,resolver);</code>
+      The event you get back from
+      <seealso marker="ose_erl_driver#erl_drv_ose_event_alloc">
+      erl_drv_ose_event_alloc</seealso> can then be used by
+      <seealso marker="erts:erl_driver#driver_select">driver_select</seealso>
+      to subscribe to signals. The first argument is just the signal number
+      that we are interested in. The second is the id that we choose to use,
+      in this case the port id that we got in the
+      <seealso marker="erts:driver_entry#start">start</seealso> callback is
+      used. The third argument is a function pointer to a function that can
+      be used to figure out the id from a given signal. The fourth argument can
+      point to any additional data you might want to associate with the event.
+      There is a complete. You can examine the data contained in the event with
+      <seealso marker="ose_erl_driver#erl_drv_ose_event_fetch">erl_drv_ose_event_fetch</seealso>
+      , eg:
+      <code>erl_drv_ose_event_fetch(event, &amp;signal, &amp;port, (void **)&amp;extra);</code>
+      example of what this could look like in
+      <seealso marker="#example">the next section</seealso>.
+      <note>It is very important to issue the driver_select call before
+      any of the signals you are interested in are sent. If driver_select
+      is called after the signal is sent, there is a high probability that it
+      will be lost.</note>
+    </p>
+    <p>
+      The other difference from unix is that in OSE the payload of the event
+      (i.e. the signal data) is already received when the ready_output/input
+      callbacks are called. This means that you access the data of a signal
+      by calling <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
+      erl_drv_ose_get_signal</seealso>. Additionally multiple signals might be
+      associated with the event, so you should call
+      <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
+      erl_drv_ose_get_signal</seealso> until <c>NULL</c> is returned.
