|
return the number pointers currently referencing this object. |
|
|
|
increment the reference count by one, indicating that this object has another pointer which is referencing it. |
|
decrement the reference count by one, indicating that a pointer to this object is referencing it. If the reference count goes to zero, it is assumed that this object is no longer referenced and is automatically deleted. |
|
decrement the reference count by one, indicating that a pointer to this object is referencing it. However, do not delete it, even if ref count goes to 0. Warning, unref_nodelete() should only be called if the user knows exactly who will be resonsible for, one should prefer unref() over unref_nodelete() as the later can lead to memory leaks. |
