hi Dave and hongjun:
We also got confused with below code. Dos it works correctly?
Maybe the dhcp_proxy_to_client_input fuction runs in the worker thread, and
it will call vlib_process_signal_event function to trigger dhcp-proccess node
in the main thread.
If it works, maybe the question of mail title could be solved. But We can't
find any other use like this until now.
dhcp_proxy_to_client_input
dhcp_client_for_us
vlib_process_signal_event (vm, dhcp_client_process_node.index,
EVENT_DHCP_CLIENT_WAKEUP, c - dcm-＞clients)

主 题 ：Re: [vpp-dev] Signal events between graph nodes within different threads
What are you trying to do?
Your description is abstract to the point where I won’t try to answer, aside
from writing that vlib_process_signal_event(...) is not your friend.
Thanks… Dave

Subject: Signal events between graph nodes within different threads
Hey all,
We have a question about signal events between graph nodes within different
threads.
Here is the scenario of use case:
We have two threads: thread 1 and thread2, which run on different VPP programs.
Thread 1 has one graph node a,
Thread 2 has another graph node b.
Now we want to signal an event from thread 1’s node a to thread 2’s node b.
Can vlib_process_signal_event achieve this?
It appears that vlib_process_signal_event can signal an event between two graph
nodes within the same thread.
If not, is there any other way to address above use case?
Thanks a lot,
Hongjun_______________________________________________
