clearing a priority_queue

[Tino]

Hopefully a simple question:

What is the best/safest/fastest way to clear/make empty a std::priority_queue?

Thanks,
Ryan

std::priority_queue myqueue;
... // fill it up

// clear it:
myqueue = std::priority_queue(); // assign an empty one to it

Doh! I forgot queues are assignable.

When you say "clear it", do you mean that I need to pop off all items? I'm
worried about proper destruction of the elements of the priority_queue. If
this is the case, doesn't

while( myqueue.size() > 0 )
myqueue.pop();

do the job? But is this the fastest way to do it? For std::vector there is
std::vector::clear, and I couldn't find anything analagous for
std::priority_queue.
myqueue = std::priority_queue(); // assign an empty one to it

No, he means that clears it (hence the colon).

HTH,
