I have a question about the allocation of arrays of classes.  How
do I increase the size of an array of classes after I've already
allocated it using "new."  For example:

If I've defined the class Test in a header file as:

	class Test {
	  public:
	     double v1;
	     // ...

	     test();
	     // ...
	}

then instantiate an array of Test using:

        int bufsize=10;
	Test *test = new Test[bufsize];

How do I increase the size of that array later on in the code when
I need a larger buffer size? (like realloc in C)

Thanks in advance for your help.
