<p>This module provides the most basic API to the
clients and servers, that are part of the Inets application,
such as start and stop. </p>

<title>COMMON DATA TYPES </title>
<p>Type definitions that are used more than once in
this module: </p>
<p><c> service() = ftpc | tftp | httpc | httpd</c></p>
<p><c> property() = atom() </c></p>
<marker id="functions"></marker>

<funcs>
<func>
<name>services() -> [{Service, Pid}]</name>
<fsummary>Returns a list of currently running services. </fsummary>
<type>
<v>Service = service()</v>
<v>Pid = pid()</v>
</type>
<desc>
<p>Returns a list of currently running services.</p>
<note>
<p>Services started as <c>stand_alone</c> will not be listed.</p>

<marker id="services_info"></marker>
</desc>
</func>
<func>
<name>services_info() -> [{Service, Pid, Info}]</name>
<fsummary>Returns a list of currently running services where
each service is described by a [{Option, Value}]
list. </fsummary>
<type>
<v>Service = service()</v>
<v>Pid = pid()</v>
<v>Info = [{Option, Value}]</v>
<v>Option = property()</v>
<v>Value = term()</v>
</type>
<desc>
<p>Returns a list of currently running services where each
service is described by a [{Option, Value}] list. The
information given in the list is specific for each service
and it is probable that each service will have its own info
function that gives you even more details about the
service.</p>
<marker id="service_names"></marker>

<marker id="start"></marker>

</func>
<func>

<name>start(Type) -> ok | {error, Reason}</name>
<fsummary>Starts the Inets application. </fsummary>
<type>
<v>Type = permanent | transient | temporary</v>
</type>
<desc>
<p>Starts the Inets application. Default type
is temporary. See also
<seealso marker="kernel:application">application(3)</seealso>. </p>
<marker id="stop"></marker>

</func>
<func>

</func>
<func>
<name>start(Service, ServiceConfig) -> {ok, Pid} | {error, Reason}</name>
<name>start(Service, ServiceConfig, How) -> {ok, Pid} | {error, Reason}</name>
<fsummary>Dynamically starts an inets
service after the inets application has been started. </fsummary>
<type>
<v>Service = service()</v>
<v>ServiceConfig = [{Option, Value}]</v>
<v>Option = property()</v>
<v>Value = term()</v>
<v>How = inets | stand_alone - default is inets</v>
</type>
<desc>
<p>Dynamically starts an inets service after the inets
application has been started. </p>
<note>
<p>Dynamically started services will not be handled by
application takeover and failover behavior when inets is
run as a distributed application. Nor will they be
automatically restarted when the inets application is
restarted, but as long as the inets application is up and
running they will be supervised and may be soft code
upgraded. Services started as <c>stand_alone</c>,
e.i. the service is not started as part of the inets
application, will lose all OTP application benefits such
as soft upgrade. The "stand_alone-service" will be linked to
the process that started it. In most cases some of the
supervision functionality will still be in place and in
some sense the calling process has now become the top
supervisor.</p>
</note>
<marker id="stop2"></marker>
</desc>
</func>
<func>
<name>stop(Service, Reference) -> ok | {error, Reason} </name>
<fsummary>Stops a started service of the inets application or takes
down a "stand_alone-service" gracefully.</fsummary>
<type>
<v>Service = service() | stand_alone</v>
<v>Reference = pid() | term() - service specified reference</v>
<v>Reason = term()</v>
</type>
<desc>
<p>Stops a started service of the inets application or takes
down a "stand_alone-service" gracefully. When the
<c>stand_alone</c> option is used in start,
only the pid is a valid argument to stop.</p>
