    Calling this function in my main.

    How will I call this function in my main?

    Code:
    void *quickSort( void *ptr)
    {
      struct _qs_data *data = (qs_data *) ptr;
      long left1 = data->left;
      long right1 = data->right;
      long *myArr = data->arr;
      long depth1 = data->depth;
      long result;
      qs_data var1, var2, resVal;
      pthread_t thread1, thread2;
    
      if( left1 < right1 )
        {
          resVal.arr = myArr;
          resVal.left = left1;
          resVal.right = right1;
    
          result = partition(&resVal);
    
          var1.arr = myArr;
          var1.left = left1;
          var1.right = result-1;
          var1.depth = depth1 - 1;
    
          var2.arr = myArr;
          var2.left = result+1;
          var2.right = right1;
          var2.depth = depth1 - 1;
    
          if (depth1 > 0 )
            {
              pthread_create (&thread1, NULL, &quickSort, (void *)&var1);
              pthread_create (&thread2, NULL, &quickSort, (void *)&var2);
    
              pthread_join (thread1, NULL);
              pthread_join (thread2, NULL);
            }
          else
           {
              quickSort ((void *)&var1);
              quickSort ((void *)&var2);
            }
    
          pthread_exit(0);
    
        }
      return (NULL);
    }

    Code:
    quicksort( stufftosort );

    Hope is the first step on the road to disappointment.

    By reading the function, and copying how it calls itself.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
