| Gets the pointer stored in the calling thread. | |
| void | set (T *data) |
Sets the pointer in the calling thread without calling destructor_func(). | |

Sets the pointer in the calling thread and calls destructor_func(). | |

Thread-local data pointer.
It is recommended that all instances of this class are statically allocated. The first time an instance is used (get(), set() or replace() is called) glib allocates a scarce OS resource that cannot be deallocated.

Constructor.
| destructor_func | Function pointer, or nullptr. If destructor_func is not nullptr and the stored data pointer is not nullptr, this function is called when replace() is called and when the thread exits. |

Deletes static_cast<T*>(data)
|
inline |
Gets the pointer stored in the calling thread.
nullptr is returned.

|
inline |
Sets the pointer in the calling thread and calls destructor_func().
If a function pointer (and not nullptr) was specified in the constructor, and the stored data pointer before the call to replace() is not nullptr, then destructor_func() is called with this old pointer value.
