Buffers +And Strings Overview

Description

The +central Symbian platform idiom for both strings and buffers is descriptors. +Some APIs in this group, such as Literals, Lexical Analysis, and Package Buffers +provide additional descriptor handling facilities. In some circumstances, +applications may need to manage raw data buffers directly in memory. For this, +the Dynamic Buffers and Raw Memory APIs are available.

APIs

Use the APIs as follows:

Circular +Buffers Overview

Provides a fixed length first-in first-out +queue of fixed size objects.

Descriptors +Overview

Manipulates string and data buffer.

Dynamic +Buffers Overview

Manipulates data buffers of variable length.

Lexical Analysis Overview

Provides +string analysis and string-to-number conversions.

Literals +Overview

Provides simple creation of descriptors that contain +read-only literal text.

Package +Buffers Overview

Allows any value type (T class) +to be encapsulated as a descriptor, for the purpose of inter-thread parameter +passing.

Raw +Memory Overview

Performs simple manipulations of data in memory.
