The following code shows how to fine control the enumeration process. It enumerates Production Chains for producing User output, reducing the options using a basic query, and then chooses the first one from all possibilities.
nRetVal = context.EnumerateProductionTrees(
XN_NODE_TYPE_USER, &query, possibleChains, NULL);
nRetVal = context.CreateProductionTree(selected);
