[AGENT++] thread safety

[Ramesh Kumar]

Hello

I am new to snmp++ library. I want to know whether async as well as
sync get, getnext, set etc of snmp class are thread safe. That is can
two or more threads call these functions at same time.

The documentation says that start_poll_thread() of snmp class, which
is required to handle responses is not thread safe. So only one thread
should listen for responses.

regards
Ramesh
