RE: Problems with async
Thanks for the response Niels! I was actually missing that entire loop as I thought it wasn't necessary for my case. I added in the loop as shown in the async example and now everything works! Would you happen to know the best way to get the value of the response? Right now I am using print_variable to see the results. Ex. Say I get the system description: SNMPv2-MIB::sysDescr.0 = STRING: Linux system.name kernel#...so on How can I just retrieve what comes have STRING: and store it off in I a string? Thanks!

This app is in c++, so the callback is the only method that is declared with extern C. If this is incorrect please let me know. I am not setting the void*, because I don't need to send any data to the callback. As a starting point I have a debug point on the callback method that doesn't get hit. The snmp_async_send does not show any errors being sent. What is there looks OK, but I am missing the select loop that detects that responses have been received and calls snmp_read to handle them? Have you checked with tcpdump/wireshark that the packets are flowing? /Niels -- Niels Baggesen - @home - Århus - Denmark - n...@users.sourceforge.net The purpose of computing is insight, not numbers --- R W Hamming This message is intended only for the addressee and may contain information that is company confidential or privileged.
