Detailed Description

The SnmpEventLoop class provides an EventLoop to all the MIB modules that need to communicate with XORP. The modules will use the EventLoop to instanciate listeners required for asyncronous inter-process communication with XORP.

This function provides the only way to instantiate this class, since all other constructors are private. Use it like this:

 SnmpEventLoop& e = SnmpEventLoop::the_instance();

Now use 'e' anywhere you would use an event loop in Xorp modules, for instance:

 XorpTimer xt = e.new_periodic(100, callback);

NOTE: typically you would never need to call e.run(). If you do, you should set a short timeout, since while your MIB module is blocked, you cannot process any other SNMP requests.

Returns: reference to the SnmpEventLoop used by all XORP MIB modules.

This will free the one and only instance

This is the name this class will use to identify itself in the snmpd log. Only used for debugging
