AW: [boost] shared_array.size()

Hi Joe,
 
this is not in the scope of this class. Since you cannot request the size
from an array you've allocated dynamically, the shared_array cannot report
either.
 
Greetings,
Jörg

Betreff: [boost] shared_array.size()

    I have been using the shared_ptr from "smart_ptr.hpp" and have found it
very useful.  However, I am afraid to try using the shared_array from the
same file.  The problem is that shared_array does not have a size() member
function.  This makes it very dangerous to use the shared_array if the user
doesn't know what size array it was created with, for instance if it was
returned from a function.  
 
   I think the shared_array would be much more useful with a size() member.
However,  this would necessitate changing the constructor and the reset()
function to take an extra parameter to indicate the size.  Also, it would
necessitate using a third pointer to store the size.
