Problem in subscribing the event notification

[jkcreddy]

Hi
I am using netopeer server to access libnetconf. From client i tried to subscribe to an event and sent to server through rpc as the following.

rpc = nc_rpc_get(filter);
nc_session_send_recv(session, rpc, &reply)

upto here it is working fine

rpc = nc_rpc_subscribe(NULL,NULL,NULL,NULL);
nc_session_send_recv(session, rpc, &rply)

After this system is being crashed with following info

netopeer-server[3914]: Received message (session 12): <?xml version="1.0" encoding="UTF-8"?>
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="2">
  <create-subscription xmlns="urn:ietf:params:xml:ns:netconf:notification:1.0"/>
</rpc>

Program received signal SIGSEGV, Segmentation fault.

1. How can it be solved (or do i miss anything while calling above api's).

Please help

Hi,
it should definitely not crash and we will look into it, but did you initialize libnetconf with notifications? If not, that would likely fix it.

Hi michalvasko

Thanks for your immediate reply!!!!
I found that initialization of notification is missing(due to slight code change in internal.c file).
Now it is working fine:)
Thanks once again.
