$currchans([<server refnum>])

Returns the current channels for each window connected to <server refnum>. If <server refnum> is -1, then $lastserver() is assumed.

If no arguments are passed, all current channels are returned.

This function returns each argument as “<server refnum> <channel>” in double quotes.

eval echo $currchans(1)    /* returns "1 #epic" "1 #unix" */

(assuming there are two windows connected to server 1, with #epic in one window and #unix in the other)
