title: _sopen_s and fopen .. what to be used?
body: <p>I want to read a file from a driver for 3rd party application 
  (simple C absed DLL runnning in user space but under control of the 3rd party application)</p>
  
  <p>This file will be written to by an separate C# application.</p>
  
  <p>What shall I use so that I do not face any problems?</p>
  
  <p>What is advantage of using _sopen_s over fopen, I understand the former is more secure but what is the feature of 'sharing' it supports?</p>
  
  <p>I did Google it out number of tims but could not find it.</p>
