I have a class member (boost::shared_ptr):

class XYZ { private: boost::shared_ptr<int> m_pBuff; // other member ... public: void func(int n) { m_pBuff.reset(new int[n]); // or m_pBuff = boost::shared_ptr<int>(new int[n]) ...; } // other functions ... }

The func(n) will be called many times inside / outside the class. Can I use shared_ptr here like: m_pBuff.reset(new int[n]); or m_pBuff = boost::shared_ptr<int>(new int[n]);

I tried both and get error said heap corruption

The error is passing an array to a shared_ptr. Take a look at shared_array ;-) HTH, Kris

Hello young shared_ptr holds pointers to dynamically allocated arrays. shared_ptr uses "delete ptr;" to clean-up when the pointer is no longer referenced/goes out of scope. Use shared_array or scoped_array, which correctly use delete[] ptr. On Fri, Feb 1, 2013 at 11:05 AM, young <yqin_99@yahoo.com> wrote:
