Get network information with the SIGAR API

SIGAR (full Name System Information Gatherer and Reporter, which is the Systems information Collection Report), provides an open source, cross-platform API for collecting computer hardware and operating system information (the API's underlying interface is written in C). This article shows you how to get network information with the SIGAR API:
