From 99d0bccd350cd42941c195667a5733ca6a4368a4 Mon Sep 17 00:00:00 2001 From: Mark Michelson Date: Thu, 7 Aug 2014 19:26:32 +0000 Subject: Add support for RFC 4662 resource list subscriptions. This commit adds the ability for a user to configure a resource list in pjsip.conf. Subscribing to this list simultaneously subscribes the subscriber to all resources listed. This has the potential to reduce the amount of SIP traffic when loads of subscribers on a system attempt to subscribe to each others' states. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@420384 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- include/asterisk/res_pjsip_presence_xml.h | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'include/asterisk/res_pjsip_presence_xml.h') diff --git a/include/asterisk/res_pjsip_presence_xml.h b/include/asterisk/res_pjsip_presence_xml.h index 8318067ad..add5f8918 100644 --- a/include/asterisk/res_pjsip_presence_xml.h +++ b/include/asterisk/res_pjsip_presence_xml.h @@ -16,6 +16,21 @@ * at the top of the source tree. */ +/*! + * \brief The length of the XML prolog when printing + * presence or other XML in PJSIP. + * + * When calling any variant of pj_xml_print(), the documentation + * claims that it will return -1 if the provided buffer is not + * large enough.
