To manage an object: ```cpp // Before MyClass* ptr = new MyClass(); SrsAutoFree(MyClass, ptr); ptr->do_something(); // Now SrsUniquePtr<MyClass> ptr(new MyClass()); ptr->do_something(); ``` To manage an array of objects: ```cpp // Before char* ptr = new char[10]; SrsAutoFreeA(char, ptr); ptr[0] = 0xf; // Now SrsUniquePtr<char[]> ptr(new char[10]); ptr[0] = 0xf; ``` In fact, SrsUniquePtr is a limited subset of SrsAutoFree, mainly managing pointers and arrays. SrsUniquePtr is better than SrsAutoFree because it has the same API to standard unique ptr. ```cpp SrsUniquePtr<MyClass> ptr(new MyClass()); ptr->do_something(); MyClass* p = ptr.get(); ``` SrsAutoFree actually uses a pointer to a pointer, so it can be set to NULL, allowing the pointer's value to be changed later (this usage is different from SrsUniquePtr). ```cpp // OK to free ptr correctly. MyClass* ptr; SrsAutoFree(MyClass, ptr); ptr = new MyClass(); // Crash because ptr is an invalid pointer. MyClass* ptr; SrsUniquePtr<MyClass> ptr(ptr); ptr = new MyClass(); ``` Additionally, SrsAutoFreeH can use specific release functions, which SrsUniquePtr does not support. --------- Co-authored-by: Jacob Su <suzp1984@gmail.com> |
