 * This example opens up a capture file found in jNetPcap's installation

 * allocate new memory to store header and packet buffer data and perform the

Fast PcapDumper API


1.1 - Getting Around

  +-> jnetcap - this is the main libpcap wrapper package. It contains
      +         all of the API for accessing libpcap functionality.
      |         These classes and methods do very little of their own
      |         logic and simply pass your requests over to native
      |         libpcap which handles those the requested actions.
      +-> winpcap - extension to libpcap wrapper that provides WinPcap 
      |          functions. This is operating system dependent package
      |          and you must use WinPcap.isSupported()JBufferJConfig
