I've got 5.1.3.1 sources and I can't yet find this function or doc for it. (Blast being a newbie.) RTFM'ing and STFW'ing, too.

I'm writing an app that the users will interact with as a binary only, so it's effectively irrelevant how I do it except I'd like to do it the library way. I'd really like to find out more about _netsnmp_udp_sockopt_set(), if possible. I've checked the library images, as well.
