get_node() is what you were looking for, but...

(and the rest is struct tree walking when necessary)

Ah.  Then I'd require the MIB name to always be first (though you could
define a special MIB name of "ANY" to allow for smart searching like
ANY.ifIndex == 3 if you are using a MIB loaded that lets you request a
node name from anywhere in the tree structure like Net-SNMP does; I
don't remember if libsmi allows this or not).
