title: Why use conio.h?
body: <p>I often see people use the header file of <code>conio.h</code> in C and C++, although  I can´t see any major benefits in use of the functions inside of <code>conio.h</code> in comparison to the standard library functions. <code>conio.h</code> has furthermore the disadvantages of being dependent on the Windows/MS-DOS environment and not being part of the C standard.</p>
  
  <ul>
  <li>What is the reason to choose functions of <code>conio.h</code>?</li>
  <li>What do functions inside of <code>conio.h</code> provide, what the functions of the standard C libraries can't?</li>
  <li>Why to choose the <code>conio</code> library?</li>
  </ul>
