Declaration of W3C Reference Library UTILITIES

The Utility modules are mostly container modules, dynamic strings and otherstuff that you can't live without when building applications. The modules are used by the core part of the W3C Reference Library but can also be used by the application. See also the main Library include file called WWWLib.h which contains all converters and protocol modules known to the Library. You can include this one if the application is to use all the functionality of the Library.

#define WWWUTIL_H

System dependencies

The tcp.h file includes system-specific include files and flags for I/O to network and disk. The only reason for this file is that the Internet world is more complicated than Posix and ANSI.
#include "tcp.h"

Library Includes

#ifdef __cplusplus
extern "C" { 
#endif

Basic Macros etc

This module includes file contains things we need everywhere, generally macros for declarations, booleans, etc.
#include "HTUtils.h"

Dynamic Arrays

This module implements a flexible array of pointers. It is a general utility module. An array is a structure which may be extended. These routines create and append data to arrays, automatically reallocating them as necessary. It is garanteed that the last entry in an array is NULL
#include "HTArray.h"

Association Lists

This is a small module build on top of the HTList module that provides a way to store Name-Value pairs in an easy way.
#include "HTAssoc.h"

Atoms

Atoms are strings which are given representative pointer values so that they can be stored more efficiently, and comparisons for equality done more efficiently. The pointer values are in fact entries into a hash table.
#include "HTAtom.h"

Dynamic Strings

A Chunk is a block wise expandable array of type (char *) and is a sort of apology for real strings in C. Chunks make it easier to handle dynamic strings of unknown size. It is often faster than using the String Copy Routines.
#include "HTChunk.h"

Linked Lists

This module provides the functionality for managing a generic list of data objects. The module is implemented as a single linked list using the scheme first in - last out (FILO).
#include "HTList.h"

Dymamic Memory Management

This module implements a dynamic memory API that is used throughout the Library. The API covers three types of functionality:
#include "HTMemory.h"

String Utilities

Routines for dynamic arrays of characters include string copy, case insensitive comparison etc.
#include "HTString.h"

UU encode and decode

File module provides functions functions for uuencode and decode strings which convert a buffer of bytes to/from RFC 1113 printable encoding format. This technique is similar to the familiar Unix uuencode format in that it maps 6 binary bits to one ASCII character (or more aptly, 3 binary bytes to 4 ASCII characters). However, RFC 1113 does not use the same mapping to printable characters as uuencode.
