boost/pending/mutable_queue missing clear() function
I notice that mutable_queue is missing a clear() function, i.e. a low overhead way of emptying the entire queue (without resorting to repeated pops). However, I think clear() can be implemented as follows: void clear() { clear(); } Which is efficient and (often) fast. I don't think there is any need to "clear" the index_array (since the constructor for mutable_queue doesn't initialize its contents) Lloyd J.

Surely that one only runs until you blow the stack. Am I missing something? -- Dave Abrahams Boost Consulting www.boost-consulting.com

No, but neither did I :) The correct code (in CVS of course) is: void clear() { c.clear(); } Doug
