|
|
// DESCRIPTION
|
|
//
|
|
// An ALToolKit is a factory that things in the ALArchive class can use
|
|
// to clone new objects. PkDecompressTools() creates a toolkit that can
|
|
// build PKWare decompressors. If your app is only going to be
|
|
// decompressing some type of objects, you can use the toolkit returned
|
|
// by this function in your ALEntryList, and avoid linking in support for
|
|
// compression objects.
|
|
//
|
|
// This toolkit will clone ALFile() and ALMemory() objects. If you don't
|
|
// want to support ALMemory objects, try PkDecompressFileTools().
|
|
//
|
|
// RETURNS
|
|
//
|
|
// A new toolkit. Note that this isn't a pointer, but rather a copy of
|
|
// a new toolkit. Usually this is copied into an existing toolkit.

// SHORT DESCRIPTION
|
|
//
|
|
// Create an entry list that uses the PKWare decompressors toolkit.
|
|
//
|
|
// C++ SYNOPSIS
|
|
//
|
|
// None. C++ programmers can create and manipulate toolkits easily.
|
|
// This isn't the case for C/VB/Delphi programmers, so we give them
|
|
// this special function.
|
|
//
|
|
// C SYNOPSIS
|
|
//
|
|
// #include "arclib.h"
|
|
//
|
|
// hALEntryList newALListPkDecompressTools( hALMonitor monitor );
|
|
//
|
|
// VB SYNOPSIS
|
|
//
|
|
// Declare Function newALListPkDecompressTools Lib "AL20LW"
|
|
// (ByVal monitor&) As Long
|
|
//
|
|
// DELPHI SYNOPSIS
|
|
//
|
|
// function newALListPkDecompressTools( monitor : hALMonitor ) : hALEntryList;
|
|
//
|
|
// ARGUMENTS
|
|
//
|
|
// monitor : A pointer to a monitor that will be used whenever we are
|
|
// processing objects in the list.
|
|
//
|
|
// DESCRIPTION
|
|
//
|
|
// C++ programmers pass a toolkit argument to the ALEntryList constructor,
|
|
// which determines what sort of compressors and storage objects they are
|
|
// expecting to use. C/VB/Delphi programmers can do the same thing as well,
|
|
// but it's a little bit harder for them. They have to manually create
|
|
// a toolkit, get its handle, then pass that handle to the constructor.
|
|
// After that, they need to destroy the toolkit.
|
|
//
|
|
// As a shortcut way to bypass all that work, we provide this function that
|
|
// creates an ALEntryList with the appropriate toolkit.
|
|
//
|
|
// RETURNS
|
|
//
|
|
// A handle to the newly created ALEntryList object.
