Overview + + This module provides asynchornous operations for handling SIP requests + in configuration file. + + It uses t_suspend() and t_continue() from TM module. + + Note that after invoking the an asyncronous operation, the processing + will continue later, in another application process. Therefore, do not + rely on variables stored in private memory, used shared memory if you + want to get values after the processing is resumend (e.g., $shv(...) of + htable $sht(...)). + +2.

Maximum value is 100. The parameter can be a + static integer or a varaible holding an integer. + + Since the SIP request handling is resumed in another process, + practically the config file execution state is lost. Therefore beware + that the execution of config after resume will end once the route block + where async_sleep() is called is finished. + + Example 1.2. async_sleep usage +... +async_sleep("4"); +send_reply("404", "Not found"); +exit; +... diff --git a/modules/async/doc/Makefile b/modules/async/doc/Makefile new file mode 100644 index 0000000..97b75e9 --- /dev/null +++ b/modules/async/doc/Makefile @@ -0,0 +1,4 @@ +docs = async.xml + +docbook_dir = ../../../docbook +include $(docbook_dir)/Makefile.module diff --git a/modules/async/doc/async.xml b/modules/async/doc/async.xml new file mode 100644 index 0000000..a722fb0 --- /dev/null +++ b/modules/async/doc/async.xml @@ -0,0 +1,37 @@ +<?xml version="1.0" encoding='ISO-8859-1'?> +<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN" +"http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd"; [ + +<!-- Include general documentation entities --> +<!ENTITY % docentities SYSTEM "../../../docbook/entities.xml"> +%docentities; + +]> + +<book xmlns:xi="http://www.w3.org/2001/XInclude";> + <bookinfo> + <title>ASYNC Module</title> + <productname class="trade">sip-router.org</productname> + <authorgroup> + <author> + <firstname>Daniel-Constantin</firstname> + <surname>Mierla</surname> + <email>[email protected]</email> + </author> + <editor> + <firstname>Daniel-Constantin</firstname> + <surname>Mierla</surname> + <email>[email protected]</email> + </editor> + </authorgroup> + <copyright> + <year>2011</year> + <holder>asipto.com</holder> + </copyright> + </bookinfo> + <toc></toc> + + <xi:include href="async_admin.xml"/> + + +</book> diff --git a/modules/async/doc/async_admin.xml b/modules/async/doc/async_admin.xml new file mode 100644 index 0000000..2506f06 --- /dev/null +++ b/modules/async/doc/async_admin.xml @@ -0,0 +1,124 @@ +<?xml version="1.0" encoding='ISO-8859-1'?> +<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN" +"http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd"; [ + +<!-- Include general documentation entities --> +<!ENTITY % docentities SYSTEM "../../../docbook/entities.xml"> +%docentities; + +]> +<!-- Module User's Guide --> + +<chapter> + + <title>&adminguide;</title> + + <section> + <title>Overview</title> + <para> + This module provides asynchornous operations for handling SIP requests + in configuration file. + </para> + <para> + It uses t_suspend() and t_continue() from TM module. + </para> + <para> + Note that after invoking the an asyncronous operation, the processing + will continue later, in another application process.
