/*
 * This file contains structures for each message type received by the Ventrilo3
 * protocol.  Each type is broken up into subtypes where applicable.  For
 * example:
 *
 * _v3_net_message_0x5d_0x04 is message type 0x5d subtype 0x04
 *
 * Where further breakdown is necessary (for instance user and channel
 * information messages), structures are defined specifically for that data.
 * That data (so far) is identical for any subtype.  Therefore, a user
 * definition in message type 0x5d subtype 0x04 is identical to a user
 * definition in type 0x5d subtype 0x01.
 *
 * To parse a packet, a smaller structure (i.e. a "type") will be recast as a
 * larger structure depending on the subtype.
 *
 * In cases where a particular value is unknown, it is marked by a name of
 * (unknown_#).  The number is arbitrary and subject to change.  If an unknown
 * value is identified, it should be pulled out of the unknown pool and named
 * appropriately.
 *
 * For questions or comments, join irc://irc.freenode.net channel #mangler
 *
 * Better documentation on these messages can be found at our wiki:
