Summary: Wrong send return test in _sess_synch_response

Initial Comment:
Hello,

First of all, thanks for the huge work!
I really appreciate it.....

This said ;), please see below the little bit of code from 
snmp_client.c.
Actually, the "if ((state->reqid = snmp_sess_send(sessp, 
pdu)) == 0)" is testing the result of the affectation 
instead of the result of the function call.
As a consequence, my IPV6 call fails with "NO-REPLY" 
while the initial pdu as never been sent.
Hope this helps,
Thanks again,

Sarah 


int
snmp_sess_synch_response(void *sessp,
                         netsnmp_pdu *pdu, netsnmp_pdu 
**response)
{
    netsnmp_session *ss;
    struct synch_state lstate, *state;
    snmp_callback   cbsav;
    void           *cbmagsav;
    int             numfds, count;
    fd_set          fdset;
    struct timeval  timeout, *tvp;
    int             block;

    ss = snmp_sess_session(sessp);
    memset((void *) &lstate, 0, sizeof(lstate));
    state = &lstate;
    cbsav = ss->callback;
    cbmagsav = ss->callback_magic;
    ss->callback = snmp_synch_input;
    ss->callback_magic = (void *) state;

    if ((state->reqid = snmp_sess_send(sessp, pdu)) == 
0) {
        snmp_free_pdu(pdu);
        state->status = STAT_ERROR;
    } else
        state->waiting = 1;

Hi, Sarah.  And warm regards.

 Which compiler ? operating system ?
and snmp library version ? are you using ?

can you enable packet print debugging to
assure that your client is transmitting the PDU ?
something like this code should turn on packet dump:

   netsnmp_ds_set_boolean(NETSNMP_DS_LIBRARY_ID,
        NETSNMP_DS_LIB_DUMP_PACKET, 1);
