title: Detection of smart card removal and insertion using PCSC in C
body: <p>I am using PCSC-lite v1.6.4 for my smartcard based application development.
  I need a way to detect as soon as smart card is removed from reader and then to detect the insertion into reader so that smartcard will be forced to complete a specific process again.</p>
  
  <p>If possible, is there any interrupt/event based way instead of simple polling?</p>
