then, timeout WILL exponentially backoff in the future release of net-snmp?
is it better if exponentially backoff ?
why the comments in snmp_api.h ?
struct snmp_session {
/*
* Protocol-version independent fields
*/
/** snmp version */
long version;
/** Number of retries before timeout. */
int retries;
/** Number of uS until first timeout, then exponential backoff */
long timeout;
thanks.

No.
Looking at the code:
static int
snmp_resend_request(...)
{
:
rp->retries++;
result = transport->f_send(...);
:
gettimeofday(&now, (struct timezone *) 0);
tv = now;
tv.tv_usec += rp->timeout; <=====
rp->expire = tv;
}
The same timeout value is added each time.
No back-off algorithm is applied.
