This document provides an overview of literals.
Literal descriptors are not strictly part of the Descriptors API, as they are not derived from the descriptor type base class TDesC . However, they have conversion operators so that they can be passed to any functions which take const TDesC& or const TRefByValue<const TDesC> parameters.
The API has two key concepts: literal descriptor, and literal descriptor constructor macro.
The literal descriptor stores literal text and provides operators to convert the text into a standard descriptor.
Literal descriptor constructor macro
The literal descriptor constructor macro provides a simple way to create a literal descriptor.
The constructor macro is provided by _LIT16 for wide strings, and _LIT8 for narrow strings. In Unicode builds, _LIT is equivalent to _LIT16 .
