<H2>Overview</H2>
|
|
|
|
fgbzip2 is a parallel implementation of bzip2 block-sorting file compressor that uses tbb::flow.
|
|
The output of this application is fully compatible with bzip2 v1.0.6 or newer.
|
|
|
|
<P><I>
|
|
This example includes software developed by Julian R Seward. See
|
|
<A HREF=#copyright>here</A> for copyright information.
|
|
</I></P>
|
|
|
|
It exemplifies the async_node CPF, among others.
|
|
|
|
<p>This example uses C++11 lambda expressions. Specifying a compiler option such as -std=c++11 or similar might be necessary in order to build the example.
|
|
For more information please refer to the documentation for the compiler you use.</p>
