Can a session created with Single Session API be used by multiple threads?

Hello,

Sorry about a mistake in my previous email. When I said "Single API" I 
meant Single Session API. Could someone please help me with following 
questions:
1. Can I use Single Session API to create/open a session in main thread 
then let the session been used by a thread pool in an application 
program (not a snmp agent)?
2. If a session can NOT be shared by MT even with Single Session APIs, 
can each thread of thread pool create multiple sessions (using different 
session to send requests to different agent)?
3. If 1&2 are both not thread safe, does that mean I can only use one 
session per thread with Single Session APIs?

Your help would be very appreciated.

Thanks,
Xiangyang
