+literal text</title><shortdesc>Constant literals are objects containing constant literal text

+<p>They are also referred to as <i>literal descriptors</i>. They are not true
+descriptors, they are <i>not</i> derived from the descriptor classes, but
+they do have conversion operators so that they can be passed to any function
+which takes a <codeph>const TDesC16&amp;</codeph> type, a <codeph>const TDesC8&amp;</codeph> type
+or a <codeph>const TDesC&amp;</codeph> type. </p>
+<p>Constant literal descriptors are constructed using the macros: </p>
+<ul>
+<li id="GUID-9C594461-1222-525B-B335-354CD88B10E8"><p> <codeph>_LIT16</codeph>  </p> </li>
+<li id="GUID-6B39451F-9F57-5B07-9092-6F4AFD0584F6"><p> <codeph>_LIT8</codeph>  </p> </li>
+<li id="GUID-32945A96-0230-5BCF-8504-738DD5608D57"><p> <codeph>_LIT</codeph>  </p> </li>
+</ul>
+<p>The <codeph>_L16</codeph>, <codeph>_L8</codeph> and <codeph>_L</codeph> macros,
+which perform a similar function, are retained for compatibility purposes,
+but all production code that requires literal text should use literal descriptors. </p>
+<section id="GUID-7CDEA4A3-7C16-4833-B048-2C08BDA04DA0"><title>_LIT16</title> <p>This macro constructs the 16 bit variant
+constant literal descriptor for Unicode strings. The literal descriptor object
+is an instance of a <codeph>TLitC16</codeph> class and the macro generates <codeph>const
+static           TLitC16</codeph> in the C++ code. </p> </section>
+<section id="GUID-A1FAD942-4009-43A2-B95B-FDB221656645"><title>_LIT8</title> <p>This macro constructs the 8 bit variant constant
+literal descriptor for non-Unicode strings. The literal descriptor object
+is an instance of a <codeph>TLitC8</codeph> class and the macro generates <codeph>const
+static           TLitC8</codeph> in the C++ code. </p> </section>
+<section id="GUID-285C1C21-C840-4A97-992B-F3F95D30F94B"><title>_LIT</title> <p>This macro constructs the build independent
+type constant literal descriptor. The literal descriptor object is an instance
+of a <codeph>TLitC</codeph> class and the macro generates <codeph>const static
+          TLitC</codeph> in the C++ code. By using this type, the appropriate
+variant, either 16 bit or 8 bit is selected at build time depending on whether
+the <codeph>_UNICODE</codeph> macro has been defined or not. </p> </section>
