PrcStructure Example CPP

C++ Example - PrcStructure

// ##################################################################################

// The first function here PrcStructure(), contains a series of

// function calls leading upto the main function call, the second function

// within this file ( PrcStructurePart() ).

// which contains the answer that we are looking for.

// The first function here is simply an example of how to construct the parameters

// in order acquire either a string Key (that is to be passed to other functions)

// or a computed result.

// If you are viewing this source code from the chm or web help file you can use the

// outlining features to collapse certain sections of the code for better readability.

// The helper files are optional and you can include only those files needed for your functionality
