C processes in Linux

There are several ways of creating a new process.

• Most used:
  • fork system call family ("clone" a runnning process to two running instances of the same code)
  • exec system call family (Execute a file)
• But also:
  • clone system call (Like fork - but more advanced)
  • system and popen system call (Can give security issues)
