Invalidating iterators c
The example below shows how the method is called by the producer thread in order to insert a new item into the buffer.The method locks the mutex and waits until there is a space for the new item.Moreover, the uninitialized memory allocated by in the debug mode.This can help the programmer when debugging the code to recognize the initialized memory from the uninitialized. The debug support is enabled only in the debug mode (when the can be inferred from the assertions.
The mutual exclusion between the threads can be achieved by wrapping operations of the underlying - the old element is being overwritten by the new one.
If such a controlling mechanism had been enabled, it would just complicate the matters and the usage of the would be probably less straightforward.
