You can still do that. After pfMalloc your next step is to do:

for(int i=0; i<arraysize; i++)
  dcs[i] = new pfDCS;

You now have an array of pointers of pfDCS in C++;

And don't forget to pfDelete them when you are finished:

for(int i=0; i<arraysize; i++)
   pfDelete(dcs[i]);

pfFree(dcs);

PS: allocating an array is such a way is not the same as doing:
    dcs = new pfDCS[arraySize]; which is not safe at all.
