Hi
I tried to compile the module as a separate agentx subagent (which it
should be in the final application) and my problem disappeared and i
works fine now. :)
I have another question: I'd like to control when the cache is flushed.
If I set the following cache flags the cache will never be flushed, right?
NETSNMP_CACHE_DONT_FREE_BEFORE_LOAD
NETSNMP_CACHE_DONT_FREE_EXPIRED NETSNMP_CACHE_DONT_AUTO_RELEASE
But how do I flush the cache manually?
The reason for this is that in my application the table data should
only be fetched (from an external source) when there's new data
available. My idea is to check a flag in my _cache_load routine and
only if new data is availble the table data should be loaded else the
old data present in the table should be used. But before I can load
new data into the table I need to flush the old data.
Thanks,
Jon Neerup Lassen
