handler chain.
netsnmp_mode_handler_list * netsnmp_mode_end_call_add_mode_callback
(netsnmp_mode_handler_list *endlist, int mode, netsnmp_mib_handler

*reqinfo, netsnmp_request_info *requests)
Detailed Description
At the end of a series of requests, call another handler hook.
Handlers that want to loop through a series of requests and then
receive a callback at the end of a particular MODE can use this helper
to make this possible. For most modules, this is not needed as the
handler itself could perform a for() loop around the request list and
then perform its actions afterwards. However, if something like the
serialize helper is in use this isn't possible because not all the
requests for a given handler are being passed downward in a single
group. Thus, this helper *must* be added above other helpers like the
serialize helper to be useful.
Multiple mode specific handlers can be registered and will be called in
the order they were regestered in. Callbacks regesterd with a mode of
NETSNMP_MODE_END_ALL_MODES will be called for all modes.
