Hi all:
I have some problem using net-snmp in multi-threads application.
my version of net_snmp is 5.5.
the application is simple, which is much like snmpdemoapp.c in the
wiki, and use the Single Session API, with several threads, each has its
session and read some information from remote host, I followed the advice in
README.thread--, invoke the snmp_sess_init() before adding task to each thread,
and insure that "_init_snmp_init_done == 1" when each thread perform its
task,but still get wrong result.
the stack:
