title: fopen with the stdin as the filename parameter
body: <p>I was requested to write a program the basically parses the file given to it, with redirecting the stdin, like this:<br>
  myProg param1 param2 param3 &lt; theFileToParse  </p>
  
  <p>I'm trying to use the fopen function in order to open the given file, but i don't understand what should i give it in the 'const char * filename' argument.  </p>
