How to use <unistd.h> library in visual studio?

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

io.h is the Visual Studio equivalent of unistd.h.

If you are using Visual Studio, it probably means you are targetting Windows...? fork() is not part of Windows API, you must then find another way to create a new process:

  • Directly use Windows API: CreateProcess
  • Use a cross-platform library (that will callCreateProcess on Windows and probably fork on Linux. Have a look at Boost.Process for instance (but there's probably others, like Qt's QProcess

I would personnaly recommand the second approach (I use Boost.Process).
