! 17: The Basic Utility modules are mostly container modules, dynamic strings and
! 18: other stuff that you can't live without when building applications. The modules
! 19: are used by the core part of the W3C Reference Library but can also be used
! 20: by the application. See also the main Library include file called
! 21: <A HREF="WWWLib.html">WWWLib.h</A> which contains all converters and protocol
! 22: modules known to the Library. You can include this one if the application
! 23: is to use all the functionality of the Library.

! 56: Dynamic Arrays
! 57: </H3>
! 58: <P>
! 59: This module implements a flexible array of pointers. It is a general utility
! 60: module. An array is a structure which may be extended. These routines create
! 61: and append data to arrays, automatically reallocating them as necessary.
! 62: It is garanteed that the last entry in an array is <B>NULL</B>

! 70: This is a small module build on top of the <A HREF="HTList.html">HTList

! 72: way.

! 77: Atoms
! 78: </H3>
! 79: <P>
! 80: Atoms are strings which are given representative pointer values so that they
! 81: can be stored more efficiently, and comparisons for equality done more
! 82: efficiently. The pointer values are in fact entries into a hash table.

! 89: <P>
2.5 frystyk 90: A Chunk is a block wise expandable array of type (char *) and is a sort of
91: apology for real strings in C. Chunks make it easier to handle dynamic strings
2.10 ! frystyk 92: of unknown size. It is often faster than using the String Copy Routines.

! 99: <P>
! 100: This module provides the functionality for managing a generic list of data
! 101: objects. The module is implemented as a single linked list using the scheme
! 102: <EM>first in - last out (FILO)</EM>.

! 109: <P>
! 110: This module defines any memory handler to be used by libwww for allocating
! 111: and de-allocating dynamic memory. As dynamic memory may be a scarce resource,
! 112: it is required that an application can handle memory exhaustion gracefully.

! 126: UU encode and decode
! 127: </H3>
! 128: <P>
! 129: File module provides functions functions for uuencode and decode strings
! 130: which convert a buffer of bytes to/from
! 131: <A HREF="http://info.internet.isi.edu:80/in-notes/rfc/files/rfc1113.txt">RFC
! 132: 1113 </A>printable encoding format. This technique is similar to the familiar
! 133: Unix uuencode format in that it maps 6 binary bits to one ASCII character
! 134: (or more aptly, 3 binary bytes to 4 ASCII characters). However, RFC 1113
! 135: does not use the same mapping to printable characters as uuencode.
