Subject: Re: [Boost-Users] boost::shared_ptr<const T>
From: "Andrew R. Thomas-Cramer"
Is it legal to construct a boost::shared_ptr<const T> from a raw T*?
Yes, it's legal.
Neat!
On MSVC6, it produces errors when class T has an implicit destructor, but
compiles without error otherwise.
Seems to work for me; coud you post an example?
I'm using boost 1.27 and MSVC6.0. Here's example code, followed by the compiler
error:
#include
class With {
public:
With() { }
~With() { }
};
class Without {
public:
Without() { }
};
int
main() {
boost::shared_ptr<const With> pWith( new With() );
boost::shared_ptr<const Without> pWithout( new Without() );
return 0;
}
Compiling...
main.cpp
d:\projects\lib\boost\boost_1_27_0\boost\checked_delete.hpp(27) : error C2665:
