delete, 接受一个动态对象的指针,销毁该对象,并释放与之关联的内存. Smart pointers are used to make sure that an object is deleted if it is no longer used (referenced) 相对于查找和修正指针的这些错误[3]来说,制造出这些错误往往更简单; 1.1 智能指针的动态内存管理 动态内存如果忘记释放就会产生内存泄...
Usestd::shared_ptrfor Multiple Pointers to Refer to the Same Object in C++ Since the manual management of dynamic memory happens to be quite hard for real-world projects and often is the main cause of the bugs, C++ provides the concept of smart pointers as a separate library. Smart pointer...
Smart pointers automatically handle many of these problems. They are basically an object which behave like pointers i.e. wrap a bare pointer but provides extra functionality. So we should use these in place of bare pointers. Now, let us understand the basics of how smart pointers work. Please...
Smart pointers are objects which store pointers to dynamically allocated (heap) objects. They behave much like built-in C++ pointers except that they automatically delete the object pointed to at the appropriate time. Smart pointers are particularly useful in the face of exceptions as they ensure p...

看一下Ogre里面的ShagedPtr,其实就是一个Smart Pointers。下面的代码是删去了原有注释的。现不谈里面的MUTEX。 #ifndef __SharedPtr_H__ #define __SharedPtr_H__ #include "OgrePrerequisites.h" namespace Ogre { template<class T> class SharedPtr { ...
Smart pointers do not replace plain pointers -- that's a common misconception. If it isn't desirable to transfer or share ownership, call get and pass the result. Only work with smart pointers to share or transfer ownership -- this should be fairly uncommon, which is fortunate because it...
asResource*, but then we might forget to delete r later, which is the whole point of using smart pointers in the first place. So that’s out. Returning the Auto_ptr1 by value is the only option that makes sense -- but then we end up with shallow copies, duplicated pointers, and ...
