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. // // EXAMPLE // // SEE ALSO // // REVISION HISTORY // // February 14, 1996 2.0A : New Release // AL_LINKAGE ALToolKit AL_FUNCTION PkDecompressFileTools() /* Tag public function */ { return ALPkDecompressor() + ALCopyDecompressor() + ALFile(); } // // NAME // // newALListPkDecompressFileTools() // // PLATFORMS/ENVIRONMENTS // // Console Windows PM // C VB Delphi // // SHORT DESCRIPTION // // Create an entry list that uses the PKWare and ALFile toolkit. // // C++ SYNOPSIS // // None.

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. // // EXAMPLE // // SEE ALSO // // REVISION HISTORY // // February 14, 1996 2.0A : New Release // #if !defined( AL_NO_C ) extern "C" AL_LINKAGE hALEntryList AL_FUNCTION newALListPkDecompressFileTools( hALMonitor monitor ) /* Tag public function */ { if ( monitor ) AL_ASSERT_OBJECT( monitor, ALMonitor, "newALListPkDecompressFileTools" ); return (hALEntryList) new ALEntryList( (ALMonitor *) monitor, PkDecompressFileTools() ); } #endif
