[JDEV] Jabber Client - Sockets problem

[Jonathan Augenstine]

If you are masochistic enough, as I was, to want to write your own
client using sockets, you should check out ACE.  It is a great real time
communications package that wraps the low level stuff so you can focus
on the application.  Very active, well maintained, cross platform (I
have identical Jabber code running on WIN32 and Solaris), and nicely
documented.  It is opensource.  You can find it at the link below:

First - You may want to look at some libraries that already do that,
jabberoo (Linux, win32).  JabberCOM (COM based win32) and there are some
java libs as well.

If you need to make your own, you should look at jabberoo for some
ideas.

I assume your lib is based on a select (or poll) loop, when select (or
poll) returns with > 0 you need to read (or recv) on the active file
descriptor(s).  Both functions (read or recv) will work for you in linux
but you need to use recv in win32.

So you create a static buffer of whatever size you want (4 or 8k is
usually good).  You pass that to recv which fills it.  Your lib needs to
employ a SAX XML parser which you can pass the recv'd data to.  If the
data in the recv kernel buffer is larger than you can read you will get
the rest on the next time through the select loop, pass it on to the
parser.

At that point the lib needs to use some kind of callback mechanism to
call the app that is using the lib.
