Dear Dave,
Thank you for your suggestions.But I am afraid simply using :
snmp_send( ss1, pdu );
snmp_send( ss2, pdu );
snmp_send( ss3, pdu );
can't send a trap with content pdu to different destinations ,because the
routine snmp_send will free pdu automaticlly if succeed.I have thought about
this too,but it is the fact.So I should rebuild the same trap with the same
"pdu" so as to send it to different receivers.The effiency is very low!But I
think it is necessary if using this method,isn't it?

For each destination, you'll need to open a new session.
But you can use the same template for each of them.
Something like:
session.version = SNMP_VERSION2c;
session.community = "public";
session.remotepeer = "trapdest1:162";
ss1 = snmp_open( &session );
session.remotepeer = "trapdest2:162";
ss2 = snmp_open( &session );
session.remotepeer = "trapdest3:162";
ss3 = snmp_open( &session );
pdu = snmp_pdu_create(SNMP_MSG_TRAP2);
snmp_send( ss1, pdu );
snmp_send( ss2, pdu );
snmp_send( ss3, pdu );
If you're going to be sending several traps to the same destinations,
then you could re-use the ss1,ss2,ss3 structures from one time
to the next - rather than re-creating them every time.
Note that the code above is a gross oversimplification, and is
almost certainly not correct (as well as being incomplete). But
it should give you the basic idea.
