StuffIt SDK Specifications

The SDK provides C interface and includes dynamic libraries only. StuffIt SDK Mac OS X 10.4 and higher and was designed to work with Xcode 2.5 and higher and the following Windows platforms: NT, 2000, XP, 2003 and Vista. The SDK was designed to work with MS Visual Studio 2005 Visual C++ 8.0.

To improve compression/expansion performance SDK has an option to create optimum number of threads per operation on machines with multiple processors and/or hyper-threading processors. Thus, SDK will create four threads for a single compression operation on a machine with four processors. On average you will see 20% to 85% time improvement compared to single thread compression depending on the machine characteristics and the number of processors.

StuffIt SDK multi-threading implementation is based on PThreads and uses QpThread library designed and implemented by Pavel Krauz Copyright (C) 1999. The thread library is free software and distributed under the Lesser GNU Public License (LGPL).
