/*****************************************************************************
* RRDLIB .NET Binding Test
*****************************************************************************
* Created 2010/06/29 by Chris Larsen
* Updated 2011/04/15 - Modified the string arrays to use pointers as the old
* automatic marshalling of strings didn't seem to work well with 1.4.5
*
* This project tests the .NET binding library by creating an rrd, inserting
* data, fetching data, creating graphs, dumping and exporting the data to
* XML, then restoring from an XML file. The examples follow the tutorial
* written by Alex van den Bogaerdt found at
* https://oss.oetiker.ch/rrdtool/tut/rrdtutorial.en.html
