MAX_PACKET_LEN

#define MAX_PACKET_LEN   10000

Familiarize yourself with RFC1035 if you want to know what all the variable names mean.

This file hides most of the dirty work all of this code depends on the buffer space a packet is in being 4096 and zero'd before the packet is copied in also conveniently decodes srv rr's, type 33, see RFC2782 Should be reasonably large, for UDP
