Moving From system() calls to Rcpp Interfaces

Over on the Data Driven Security Blog there’s a post on how to use Rcpp to interface with an external library (in this case ldns for DNS lookups). It builds on another post which uses system() to make a call to dig to lookup DNS TXT records.

The core code is below and at both the aforementioned blog post and this gist. The post walks you though creating a simple interface and a future post will cover how to build a full package interface to an external library.
