Fetch current node and channelid

[delicjous]

Hi everyone,

I want to do my first real mod includes an API call.
I read about a mod-request which should list all Moderators of a Forum.
Thought it should be easy enough to start with.

But I did'nt find the API-call of the current channel and nodeid.
I need to set the current nodeid and current channelid to a variable

$nodeid =?
$channelid =?

I would show all usernames where moderator for nodeid and nodeid = channelid.
So if the User is moderator in nodeid = 3 (db-table moderator) the Moderatorbar should be visible at channel 3 pages.

Could anybody help me please :-)
