   PDP CORE API OVERVIEW

   pdp_packet_* : packet methods, first argument is packet id

      new:                construct a raw packet (depreciated)
      new_*:              construct packet of specific type/subtype/...
      mark_unused:        release
      mark_passing:       conditional release (release on first copy ro/rw)
      copy_ro:            readonly (shared) copy
      copy_rw:            private copy
      clone_rw:           private copy (copies only meta data, not the content)
      header:             get the raw header (t_pdp *)
      data:               get the raw data (void *)
      pass_if_valid:      send a packet to pd outlet, if it is valid
      replace_if_valid    delete packet and replace with new one, if new is valid
      copy_ro_or_drop:    copy readonly, or don't copy if dest slot is full + send drop notify
      copy_rw_or_drop:    same, but private copy
      get_description:    retrieve type info
      convert_ro:         same as copy_ro, but with an automatic conversion matching a type template
      convert_rw:         same as convert_ro, but producing a private copy

   pdp_pool_* : packet pool methods

      collect_garbage:    manually free all unused resources in packet pool

   pdp_queue_* : processing queue methods

      add:                add a process method + callback
      finish:             wait until a specific task is done
      wait:               wait until processing queue is done

   pdp_control_* : central pdp control hub methods

      notify_drop:        notify that a packet has been dropped

   pdp_type_* : packet type mediator methods

      description_match:   check if two type templates match
      register_conversion: register a type conversion program



   NOTE: it is advised to derive your module from the pdp base class defined in pdp_base.h
         instead of communicating directly with the pdp core
