I am going to implement Dekker's algorithm to guarantee mutex exclusion between P1 and P2.

void p1()
     {
         "Dekker's algorithm ..."
     }

void p2()
    {
         "Dekker's algorithm ..."
    } 


   void main()
  {
      parbegin(p1,p2);
       ...
  }

Should I use "fork" or others?

Thanks!

Well. No one can answer this simple answer. I am despaired. It looks like no expert here.
