Last change on this file since 256899f was f0cb961, checked in by Wilmer van der Gaast <wilmer@…>, at 2007-04-19T06:03:43Z
More API changes: buddy list management. imcb_add_buddy() is now a real callback, it's only called from inside IM-modules. This makes sure a buddy only gets added to the BitlBee structures if the add was successful. This gets rid of the weirdness described in #55. Unfortunately for now this change breaks A) automatic renaming of ICQ contacts (if there are names stored in the contact list) B) add -tmp.
