How to run a function in background?

I want to run a C function in background but I want it to keep it running when the main function exits.

I tried following:

  1. pthread_detach, a detached thread exits if the main function calls exit() instead of pthread_exit.
  2. deamon(): It runs the code in background but not in parallel.

So, what is the simplest way to run a C function in parallel/background even after my main function exits?

Once main returns OS will delete all threads within process. To continue thread use fork to create child process.

Exit main() by calling pthread_exit().
