How to use <unistd.h> library in visual studio?
<p>I am faced with a OS experiment to develop a Unix shell. In order to create a new process, I have to use the <code>fork()</code> function. However, the <code>fork()</code> function is defined in <code>&lt;unistd.h&gt;</code>, and I can not use it in Microsoft Visual Studio. Is there any way to solve this? </p>
