.SH "NAME"
Net::XMPP::Protocol \- XMPP Protocol Module
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Net::XMPP::Protocol is a module that provides a developer easy
access to the \s-1XMPP\s0 Instant Messaging protocol. It provides high
level functions to the Net::XMPP Client object. These functions are
inherited by that modules.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Protocol.pm seeks to provide enough high level APIs and automation of
the low level APIs that writing a \s-1XMPP\s0 Client in Perl is trivial. For
those that wish to work with the low level you can do that too, but
those functions are covered in the documentation for each module.
.PP
Net::XMPP::Protocol provides functions to login, send and receive
messages, set personal information, create a new user account, manage
the roster, and disconnect. You can use all or none of the functions,
there is no requirement.
.PP
For more information on how the details for how Net::XMPP is written
please see the help for Net::XMPP itself.
.PP
For more information on writing a Client see Net::XMPP::Client.
.SS "Modes"
.IX Subsection "Modes"
Several of the functions take a mode argument that let you specify how
the function should behave:
.IP "block" 4
.IX Item "block"
send the packet with an \s-1ID,\s0 and then block until an answer
comes back. You can optionally specify a timeout so that
you do not block forever.
.IP "nonblock" 4
.IX Item "nonblock"
send the packet with an \s-1ID,\s0 but then return that id and
control to the master program. Net::XMPP is still
tracking this packet, so you must use the CheckID function
to tell when it comes in. (This might not be very
useful...)
.IP "passthru" 4
.IX Item "passthru"
send the packet with an \s-1ID,\s0 but do \s-1NOT\s0 register it with
Net::XMPP, then return the \s-1ID. \s0 This is useful when
combined with the XPath function because you can register
a one shot function tied to the id you get back.

, , and

with an \s-1ID\s0 which is found in the
registered \s-1ID\s0 list (see RegisterID
below) then it is not sent to
these functions, instead it
is inserted into a \s-1LIST\s0 and can
be retrieved by some functions
we will mention later.
.Sp
send and receive are used to
log what \s-1XML\s0 is sent and received.
update is used as way to update
your program while waiting for
a packet with an \s-1ID\s0 to be
returned (useful for \s-1GUI\s0 apps).
.Sp
A major change that came with
the last release is that the
session id is passed to the
callback as the first argument.
This was done to facilitate
the Server module.
.Sp
The next argument depends on
which callback you are talking
about. message, presence, and iq
all get passed in Net::XMPP
objects that match those types.
send and receive get passed in
strings. update gets passed
nothing, not even the session id.

that you are available. If you
provide a hash, then it will pass
that hash to the \fISetPresence()\fR

takes all of the information and
builds a Net::XMPP::IQ::Auth packet.
It then sends that packet to the
server with an \s-1ID\s0 and waits for that
\&\s-1ID\s0 to return. Then it looks in
resulting packet and determines if
authentication was successful for not.
The array returned from AuthSend looks
like this:

If type is \*(L"ok\*(R" then authentication
was successful, otherwise message
contains a little more detail about the
