Python API to C++ -返回指向对象的指针，而不是整个对象

#include <memory>

class MyClass {
public:
    int data;
};

std::shared_ptr<MyClass> createObject() {
    return std::make_shared<MyClass>();
}

std::shared_ptr<MyClass> obj = createObject();
if (obj) {
    // 安全地访问obj
} else {
    // 处理空指针情况
}

template <typename T>
class SafePointer {
public:
    explicit SafePointer(T* ptr) : ptr_(ptr) {}
    ~SafePointer() { delete ptr_; }
    T* get() const { return ptr_; }
private:
    T* ptr_;
};

#include <iostream>
#include <memory>

class MyClass {
public:
    int data;
    MyClass(int d) : data(d) {}
};

std::shared_ptr<MyClass> createObject(int value) {
    return std::make_shared<MyClass>(value);
}

int main() {
    std::shared_ptr<MyClass> obj = createObject(42);
    if (obj) {
        std::cout << "Data: " << obj->data << std::endl;
    } else {
        std::cout << "Object creation failed." << std::endl;
    }
    return 0;
}
