.SH MEMBER FUNCTION DOCUMENTATION
.SH "QNPStream::QNPStream ( QNPInstance * in,const char * mt, _NPStream * st, bool se )"
Creates a stream. Plugins should not call this, but rather QNPInstance::newStream() if a stream is required.
.SH "QNPStream::~QNPStream ()"
Destroys the stream.
.SH "bool QNPStream::complete () const"
Returns TRUE if the stream has received all the data from the source.
.SH "uint QNPStream::end () const"
Returns the length of the stream (???).
.SH "QNPInstance* QNPStream::instance ()"
Returns the QNPInstance for which this stream was created.
.SH "uint QNPStream::lastModified () const"
Returns the time when the source of the stream was last modified.
.SH "bool QNPStream::okay () const"
Returns TRUE if no errors have occurred on the stream.
.SH "void QNPStream::requestRead ( int offset, uint length )"
Requests the given section of the stream be sent to the QNPInstance::write() function of the instance() of this stream.
.SH "bool QNPStream::seekable () const"
Returns TRUE if the stream is seekable.
.SH "const char* QNPStream::type () const"
Returns the MIME type of the stream.
.SH "const char* QNPStream::url () const"
Returns the URL from which the stream was created.
.SH "int QNPStream::write ( int len, void * buffer )"
Writes data \fIto\fR the stream.
.SH "void QNPStream::setComplete ( bool y )"
For internal use only.
.SH "void QNPStream::setOkay ( bool y )"
For internal use only.
