 | |
| //
 | |
| // DESCRIPTION
 | |
| //
 | |
| //  An ALToolKit is a factory that things in the ALArchive class can use
 | |
| //  to clone new objects.  PkDecompressFileTools() creates a toolkit that can
 | |
| //  build PKWare decompressors.  If your app is only going to be
 | |
| //  decompressing ALFile objects, you can use the toolkit returned
 | |
| //  by this function in your ALEntryList, and avoid linking in support for
 | |
| //  compression objects, Greenleaf compressors and decompressors, and
 | |
| //  ALMemory objects.
 | |
| //
 | |
| // RETURNS
 | |
| //
 | |
| //  A new toolkit.

 | |
| // SHORT DESCRIPTION
 | |
| //
 | |
| //  Create an entry list that uses the PKWare and ALFile 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 newALListPkDecompressFileTools( hALMonitor monitor );
 | |
| //
 | |
| // VB SYNOPSIS
 | |
| //
 | |
| //  Declare Function newALListPkDecompressFileTools Lib "AL20LW"
 | |
| //    (ByVal monitor& ) As Long
 | |
| //
 | |
| // DELPHI SYNOPSIS
 | |
| //
 | |
| //  function newALListPkDecompressFileTools( 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.
