source: protocols/jabber/jabber.h @ 608f8cf

Last change on this file since 608f8cf was 608f8cf, checked in by Wilmer van der Gaast <wilmer@…>, at 2007-11-24T18:02:39Z

Added some random hash to the id= for cached XMPP packets so that packets
from other BitlBees won't be picked up accidentally. Might also want to
randomize the per-packet IDs because they're still predictable.
