I want pList to be processed in the other functions, that's why I create a
pointer pList. Just as Giovanni says, I don't want copy constructors to be
invoked many times, I don't know whether it's worthwhile or not.

If CData is not a very big object, you may consider keeping CData in list,
so having std::list< CData >.
Else, I would suggest to use boost::shared_ptr (or tr::shared_ptr when TR1
will ship as kind of "service pack" for VS2008).
e.g.

  typedef std::list< boost::shared_ptr< CData > > ListOfCData;

For more information on boost::shared_ptr, you may read here:

http://www.boost.org/libs/smart_ptr/shared_ptr.htm

For TR1 (and other interesting things) I would suggest to read Visual C++
Team's blog:

If you want to pass your list between different functions or methods, you
can use pointers or references (I would use references), e.g.

  void InitList( ListOfCData & list )
  {
     // Build your list here.
     //
     // Whatever modification you do to 'list' instance will be
     // made for the caller's list instance, because you are passing by
*reference* (the "&")
  }

  void DoSomethingOnList( ListOfCData & list )
  {
     // As before...
     list.<some method>
   }

   ListOfCData myList; // list instance
   InitList( myList );
   DoSomethingOnList( myList );
