I'm having trouble doing something like this...
void Enlarge(char *p)
{
   char *x=new char[20];
   delete[] p;
   p=x;
}
void main()
{
   char *sz=new char[10];
   Enlarge(sz);
}
Using the debugger, it looks like p does get the address of x, but after
the function, sz is the same address, an empty string?  Trying to do
it different, like this...
char *Enlarge(char *p)
{
   char *x=new char[20];
   delete[] p;
   return x;
}
void main()
{
   char *sz=new char[10];
   sz=Enlarge(sz);
}
so far seems to work, but am I even on the right track?
