Google Maps API v3: How to remove all markers?

Question

In Google Maps API v2, if I wanted to remove all the map markers, I could simply do:

map.clearOverlays();

How do I do this in Google Maps A

Answer 1

The "set_map" function posted in both answers appears to no longer work in Google Maps v3 API.

I wonder what happened

Update:

It appears Google changed their API such that "set_map" is not "setMap".
