IDA_EventDataWaitallows a
caller to wait for data from a MIB-based event queue. This function
doesn’t usually poll the agent looking for data. Instead, it waits
for the agent to tell it that data is available. This function can
only be used with certain MIB variables. In particular, it can be
used with
IDAV_MonEventAltData.One of the parameters to
IDA_EventDataWaitis a timeout
value. If the wait reaches the timeout value with no returned data,
it returns with a specific return value.
Under the covers,
IDA_EventDataWaitbuilds a
special version of a GET_BULK request containing a single repeating
variable, no instance information and a large
<max-repetitions> value. This request is sent to the agent if
the agent didn’t last return a “no data available” response. It
then waits on data from the agent for the specified timeout period.
If data becomes available before the timeout, the
application-defined
SessionRequestCallBackProccallback function is called for each
returned variable instance.
