-.SH DESCRIPTION
-The QBuffer class is an I/O device that operates on a QByteArray.
-.PP
-QBuffer is used to read and write to a memory buffer. It is normally used with a QTextStream or a QDataStream. QBuffer has an associated QByteArray which holds the buffer data. The size() of the buffer is automatically adjusted as data is written.
-.PP
-The constructor \fCQBuffer(QByteArray)\fR creates a QBuffer using an existing byte array. The byte array can also be set with setBuffer(). Writing to the QBuffer will modify the original byte array because QByteArray is explicitly shared.
-.PP
-Use open() to open the buffer before use and to set the mode (read-only, write-only, etc.). close() closes the buffer. The buffer must be closed before reopening or calling setBuffer().
-.PP
-A common way to use QBuffer is through QDataStream or QTextStream, which have constructors that take a QBuffer parameter. For convenience, there are also QDataStream and QTextStream constructors that take a QByteArray parameter. These constructors create and open an internal QBuffer.
-.PP
-Note that QTextStream can also operate on a QString (a Unicode string); a QBuffer cannot.
-.PP
-You can also use QBuffer directly through the standard QIODevice functions readBlock(), writeBlock() readLine(), at(), getch(), putch() and ungetch().
-.PP
-See also QFile, QDataStream, QTextStream, QByteArray, Shared Classes, Collection Classes, and Input/Output and Networking.
-.SH MEMBER FUNCTION DOCUMENTATION
-.SH "QBuffer::QBuffer ()"
-Constructs an empty buffer.
-.SH "QBuffer::QBuffer ( QByteArray buf )"
-Constructs a buffer that operates on \fIbuf\fR.
-.PP
-If you open the buffer in write mode (<a href="ntqfile.html#open">IO_WriteOnly</a> or IO_ReadWrite) and write something into the buffer, \fIbuf\fR will be modified.
-.PP
-Example:
-.PP
-.nf
-.br
- QCString str = "abc";
-.br
- QBuffer b( str );
-.br
- b.open( IO_WriteOnly );
-.br
- b.at( 3 ); // position at the 4th character (the terminating \\0)
-.br
- b.writeBlock( "def", 4 ); // write "def" including the terminating \\0
-.br
- b.close();
-.br
- // Now, str == "abcdef" with a terminating \\0
-.br
-.fi
-.PP
-See also setBuffer().
-.SH "QBuffer::~QBuffer ()"
-Destroys the buffer.
-.SH "QByteArray QBuffer::buffer () const"
-Returns this buffer's byte array.
-.PP
-See also setBuffer().
-.SH "bool QBuffer::setBuffer ( QByteArray buf )"
-Replaces the buffer's contents with \fIbuf\fR and returns TRUE.
-.PP
-Does nothing (and returns FALSE) if isOpen() is TRUE.
-.PP
-Note that if you open the buffer in write mode (<a href="ntqfile.html#open">IO_WriteOnly</a> or IO_ReadWrite) and write something into the buffer, \fIbuf\fR is also modified because QByteArray is an explicitly shared class.
-.PP
-See also buffer(), open(), and close().
-.SH "TQ_LONG QBuffer::writeBlock ( const char * p, TQ_ULONG len )\fC [virtual]\fR"
-Writes \fIlen\fR bytes from \fIp\fR into the buffer at the current index position, overwriting any characters there and extending the buffer if necessary. Returns the number of bytes actually written.
-.PP
-Returns -1 if an error occurred.
-.PP
-See also readBlock().
-.PP
-Reimplemented from QIODevice.
-.SH "TQ_LONG QBuffer::writeBlock ( const QByteArray & data )"
-This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
-.PP
-This convenience function is the same as calling
-\fCwriteBlock( data.data(), data.size() )\fR with \fIdata\fR.
