title: How to use SIGRTMAX and SIGRTMIN?
body: <p>I do know how signals are real time signals defined in POSIX. However I was curious to know how to use these or rather how are these signals generated? like a SIGSEGV is generated on invalid memory reference, a SIGINT is generated on a keyboard interrupt like ctrl+c.</p>
  
  <p>How are signals like SIGRTMAX and SIGRTMIN generated and used ?</p>
