/**

 * @file jpacket.c

 * @brief a jpacket is a wrapper around an xmlnode that contains an XMPP stanza

 *

 * A jpacket adds some variables to an xmlnode that contains a stanza, so that

 * jabberd is able to cache information on the stanza type (message, presence, iq)

 * that is contained in this jpacket and to further classify the presence stanzas.

 * It also adds some pointers to important data inside the xmlnode, that has

 * to be accessed often (e.g. sender and receiver of a stanza).

/**

 * create a new jpacket by wrapping an xmlnode

 *

 * @param x the xmlnode that should be wrapped

 * @return the newly created jpacket (NULL on failure)

 */

        return NULL;

/**

 * recalculate the information the jpacket holds about the stanza

 *

 * @param p the packet that should get its information recalculated

 * @return the jpacket (as given as the p parameter)
