How to open a process in C?

Question

How do I open a process that isn't connected with my program in C? for example: if the user enter the following input: start C:\Windows\calc.exe

then the calculator will open. thanks.

do you want to open the process (using OpenProcess) or do you want to start it (CreateProcess)? — Ferenc Deak, Nov 06 '12 at 07:50

Processes are not known by the C standard. You can code in standard C for a system without processes (e.g. bare metal, or MS-DOS).

On Posix compliant systems, you could use popen(3) (with fscanf and pclose).

You may also use the system(3) function.

Your operating system may have a non-Posix interface. Please dive into your system's developer documentation.
