c++ - How to make STL's priority_queue fixed-size

Question

I am creating a simple game and I use std::priority_queue for giving commands to squads (every squad has a priority_queue<command>).

Every 20 seconds a bot analyses the situation and sends commands to the priority_queue.

How can I make the priority_queue fixed-size, for example, set the size to 10? The desired effect is that when the maximum is reached, if I add 2 new commands to the queue, 2 existing commands with the lowest priority are automatically removed.

Wrap it in another class that will perform this operation for you. The Standard provides no such functionality on it's own.
