<h3>2.3.3 <a name="startingnx">Starting the NX Server</a></h3>
|
||||
<p>
|
||||
The <i>NX Server</i> is a kernel daemon that receives and serializes graphic commands.
|
||||
Before you can use the NX graphics system, you must first start this daemon.
|
||||
There are two ways that this can be done:
|
||||
</p>
|
||||
<ol>
|
||||
<li>
|
||||
<p>
|
||||
The NX server may be started in your board startup logic by simply calling the function <code> nx_start()</code>.
|
||||
The board startup logic usually resides the the <code>configs/<i>board</i>/src</code> directory.
|
||||
The boar board startup logic can run automatically during the early system if <code>CONFIG_BOARD_INITIALIZE</code> is defined in the configuration.
|
||||
Or, the board startup logic can execute under control of the application by calling the <code>boardctl(BOARDIOC_INIT, arg)</code> OS interface.
|
||||
</p>
|
||||
<p>
|
||||
The board initialization logic will run in either case and the simple call to <code>nx_start()</code> will start the NX server.
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
The NX server may also be started later by the application via the <code>boardctl(BOARDIOC_NX_START, arg)</code>
|
||||
</li>
|
||||
</ol>

None

<p>

<b>Returned Value:</b>

Zero (<code>OK</code>) is returned on success.

This indicates that the NX server has been successfully started, is running, and waiting to accept connections from NX clients.

|

<p>
|

<b>Description:</b>
|
||||
<code>boardctl()</code> is a generic NuttX interface that among many of it functions, may also be used to start the NX server.
|
||||
</p>
|
||||
In a small embedded system, there will typically be a much greater interaction between application and low-level board features.
|
||||
The canonically correct to implement such interactions is by implementing a character driver and performing the interactions via low level <code>ioctl()</code> calls.
|
||||
This, however, may not be practical in many cases and will lead to "correct" but awkward implementations.
|
||||
</p>
|
||||
<p>
|
||||
<code>boardctl()</code> is non-standard OS interface to alleviate the problem.
|
||||
It basically circumvents the normal device driver ioctl interlace and allows the application to perform direction IOCTL-like calls to the board-specific logic.
|
||||
In it is especially useful for setting up board operational and test configurations.
|
||||
</p>
|
||||
<p>
|
||||
When called with the <code>cmd</code> of <code>BOARDIOC_NX_START</code>, then the <code>boardctl()</code> will call <code>nx_start</code> indirectly on behalf of the appication.
|
||||
In this case the <code>arg</code> parameter is ignored.
|
||||
</p>
|
||||
<p>
|
||||
<b>Input Parameters:</b>
|
||||
<ul><dl>
|
||||
<dt><code>cmd</code>
|
||||
<dd> Identifies the board command to be executed
|
||||
<dt><code>arg</code>
|
||||
<dd>The argument that accompanies the command. The nature of the argument is determined by the specific command.
|
||||
</dl></ul>
|
||||
</p>
|
||||
<p>
|
||||
<b>Returned Value:</b>
|
||||
On success zero (<code>OK</code) is returned; -1 (<code>ERROR</code>) is returned on failure with the <code>errno</code> variable to to indicate the nature of the failure.
