+represent general binary data</title><shortdesc>Construct an 8 bit variant descriptor to represent general binary
+data.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The kind of data represented or contained by descriptors is not restricted
+to text. Descriptors can also handle general binary data.</p>
+<p>Binary data should always be treated as 8 bit data regardless of the build.</p>
+<p>For example, starting with an area in memory initialised with binary data
+as follows:</p>
+<codeblock id="GUID-2541B451-E008-5AD7-A8F7-4A19B76AB2A2" xml:space="preserve">TUint8 data[6] = {0x00,0x01,0x02,0xAD,0xAE,0xAF};</codeblock>
+<p>construct a modifiable buffer descriptor using the default constructor
+as follows:</p>
+<codeblock id="GUID-DDAF1F08-29EC-572F-83B0-0A4437EF1DB9" xml:space="preserve">TBuf8&lt;32&gt; buffer;</codeblock>
+<p>The following code fragment puts the binary data into the descriptor and
+appends a number of single byte values. The length of the buffer is 9, the
+maximum length is 32 and the size is 9 regardless of the build.</p>
+<codeblock id="GUID-B9AB3D57-1EFB-5A10-882E-E29301FF8759" xml:space="preserve">TInt index;
+TInt counter;</codeblock>
+<p>Text and general binary data can be freely mixed and the following code
+is acceptable:</p>
+<codeblock id="GUID-2D7B1A85-82F6-5B67-8A49-5E79745602A3" xml:space="preserve">buffer.Append('A');
+buffer.Append('B');
+buffer.Append(0x11);</codeblock>
+<p>Note that fixed length C++ arrays such as <codeph>data</codeph> above can
+be packaged inside a thin wrapper class, a <codeph>TFixedArray&lt;class T,TInt
+S&gt;</codeph> type, to guarantee that all array accesses are safe.</p>
