<p> This class is defined in the <b>TQt <a href="netscape-plugin.html#Netscape">Netscape</a> Extension</b>, which can be found in the <tt>qt/extensions</tt> directory. It is not included in the main TQt API.
<p>

The TQNPStream class provides a stream of data provided to a <a href="qnpinstance.html">TQNPInstance</a> by the browser.
<p> 
<p> Note that this is neither a <a href="qtextstream.html">TQTextStream</a> nor a <a href="qdatastream.html">TQDataStream</a>.

<h3 class=fn><a name="TQNPStream"></a>TQNPStream::TQNPStream ( <a href="qnpinstance.html">TQNPInstance</a>&nbsp;*&nbsp;in, const&nbsp;char&nbsp;*&nbsp;mt, _NPStream&nbsp;*&nbsp;st, bool&nbsp;se )
</h3>
Creates a stream. Plugins should not call this; they should call
<a href="qnpinstance.html#newStream">TQNPInstance::newStream</a>() if they need a stream.
<p> Takes a <a href="qnpinstance.html">TQNPInstance</a> <em>in</em>, MIME type <em>mt</em>, a pointer to an
_NPStream <em>st</em> and a seekable flag <em>se</em>.

<h3 class=fn><a name="~TQNPStream"></a>TQNPStream::~TQNPStream ()
</h3>
Destroys the stream.

<h3 class=fn>bool <a name="complete"></a>TQNPStream::complete () const
</h3>
Returns TRUE if the stream has received all the data from the
source; otherwise returns FALSE.

<h3 class=fn>uint <a name="end"></a>TQNPStream::end () const
</h3>
Returns the length of the stream in bytes. The function might
return 0 for streams of unknown length.

<h3 class=fn><a href="qnpinstance.html">TQNPInstance</a>&nbsp;* <a name="instance"></a>TQNPStream::instance ()
</h3>

<p> Returns the <a href="qnpinstance.html">TQNPInstance</a> for which this stream was created.

<h3 class=fn>uint <a name="lastModified"></a>TQNPStream::lastModified () const
</h3>
Returns the time when the source of the stream was last modified.

<h3 class=fn>bool <a name="okay"></a>TQNPStream::okay () const
</h3>
Returns TRUE if no errors have occurred on the stream; otherwise
returns FALSE.

<h3 class=fn>void <a name="requestRead"></a>TQNPStream::requestRead ( int&nbsp;offset, uint&nbsp;length )
</h3>
Requests the section of the stream, of <em>length</em> bytes from <em>offset</em>, be sent to the <a href="qnpinstance.html#write">TQNPInstance::write</a>() function of the
<a href="#instance">instance</a>() of this stream.

<h3 class=fn>bool <a name="seekable"></a>TQNPStream::seekable () const
</h3>
Returns TRUE if the stream is seekable; otherwise returns FALSE.

<h3 class=fn>const char * <a name="type"></a>TQNPStream::type () const
</h3>
Returns the MIME type of the stream.

<h3 class=fn>const char * <a name="url"></a>TQNPStream::url () const
</h3>
Returns the URL from which the stream was created.

<h3 class=fn>int <a name="write"></a>TQNPStream::write ( int&nbsp;len, void&nbsp;*&nbsp;buffer )
</h3>
Writes <em>len</em> bytes from <em>buffer</em> <em>to</em> the stream.
