I'm not 100% sure what your requirements are, but generally libpurple
sends a single command to the protocol plugin ("prpl") and is hands-
off after that point. The prpl should set up whatever connections it
needs and, once those are set up, finish up what it was instructed to
do ('send an IM to this buddy'). In MSN, for example,
() is passed the text along with the switchboard and does:
else if (queue)
when the switchboard is ready to send, it releases its queue of
messages. Does that answer your question?

This might be the hardest part of the plugin in terms of interfacing
with libpurple; group chat is one of the remaining areas in which
libpurple still shows its AIM roots. In AIM, there's a bright line
between one-to-one chats and multi-user chats. Other protocols, such
as MSN, which have a more dynamic concept of multi-user chats,
currently implement messaging thusly:
1) Implement the send_im function
2) Have a contact action which "initiates a multi-user chat"
3) Utilize this action to create a new PurpleConversation,
immediately adding the contact in question, and therefore setting up
for inviting more people.
chat_send and send_im can therefore be simple wrappers on some more
generic sending function, but for now both will need to be implemented.
Appropriately blurring the artificial distinction between IM and Group
Chat which currently exists would be a good thing... so if you'd like
to tackle it yourself or start a discussion on how best to accomplish
that, it would be welcomed :)

There are a number of utility functions in util.c:
purple_running_osx() (If using the define for Mac OS X, I'd use
__APPLE__ rather than __OBJC__
You might find it useful to add purple_running_windows() for
parallelism in the code... though others might consider that
unnecessary public API.

purple_blist_add_buddy() from blist.h is probably what you want.
