template<typename T >

Ptr<T> cv::makePtr ( )

makePtr<T>(...) is equivalent to Ptr<T>(new T(...)). It is shorter than the latter, and it's marginally safer than using a constructor or Ptr::reset, since it ensures that the owned pointer is new and thus not owned by any other Ptr instance. Unfortunately, perfect forwarding is impossible to implement in C++03, and so makePtr is limited to constructors of T that have up to 10 arguments, none of which are non-const references.
