Typedef Documentation

const_shared_ptr_array

using const_shared_ptr_array = std::shared_ptr<char const []>

shared_ptr_array

using shared_ptr_array = std::shared_ptr<char []>

Type alias of shared_ptr char array. You can choose the target type.

• If MQTT_STD_SHARED_PTR_ARRAY is defined, std::shared_ptr<char []> is used.
  • std::shared_ptr<char []> is supported since C++17.
• If MQTT_STD_SHARED_PTR_ARRAY is not defined (default), boost::shared_ptr<char []> is used.
  • boost::shared_ptr<char []> can be used on C++14.

make_shared_ptr_array()

inline

shared_ptr_array creating function. You can choose the target type.

• If MQTT_STD_SHARED_PTR_ARRAY is defined,
  • and if your compiler setting is C++20 or later, then std::make_shared<char[]>(size) is used.
    • It can allocate an array of characters and the control block in a single allocation.
  • otherwise std::shared_ptr<char[]>(new char[size]) is used.
    • It requires two times allocations.
• If MQTT_STD_SHARED_PTR_ARRAY is not defined (default), then boost::make_shared<char[]>(size) is used.
  • It can allocate an array of characters and the control block in a single allocation.
