In file , I find the following function:
/begin quote
template shared_ptr(Y * p, D d): px(p), pn(p, d)
{
detail::sp_enable_shared_from_this( pn, p, p );
}
/end quote
If I use it as follows:"boost::shared_ptr<Investment>
pInv(0,getRidOfInvestment)",it will not compile.But when I
use:"boost::shared_ptr<Investment>
pInv(static_cast(0),getRidOfInvestment)",it can be compiled.
The constructor's first parameter is Y*,i.e.,a pointer to Y.And 0 can be
interpreted as a pointer to Y,too. Why can't zero be treated as a pointer
to Y here?
I will be appreciative if anyone can give me some suggestions.Thank you!
