to simplify the body of the main loop of the accepting thread. Rename purge_unused() to purge_events() so one knows what the function does. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@48081 65c4cc65-6c06-0410-ace0-fbb531ad65f3

|
|

/*!
|
|
* Linked list of events.
|
|
* Global events are appended to the list by append_event().
|
|
* The usecount is the number of stored pointers to the element,
|
|
* excluding the list pointers. So an element that is only in
|
|
* the list has a usecount of 0, not 1.
|
|
*
|
|
* Clients have a pointer to the last event processed, and for each
|
|
* of these clients we track the usecount of the elements.
|
|
* If we have a pointer to an entry in the list, it is safe to navigate
|
|
* it forward because elements will not be deleted, but only appended.
|
|
* The worst that can happen is seeing the pointer still NULL.
|
|
*
|
|
* When the usecount of an element drops to 0, and the element is the
|
|
* first in the list, we can remove it. Removal is done within the
|
|
* main thread, which is woken up for the purpose.
|
|
*
|
|
* For simplicity of implementation, we make sure the list is never empty.

/*! \brief Convert the input into XML or HTML.
|
|
* The input is supposed to be a sequence of lines of the form
|
|
* Name: value
|
|
* optionally followed by a blob of unformatted text.
|
|
* A blank line is a section separator. Basically, this is a
|
|
* mixture of the format of Manager Interface and CLI commands.
|
|
* The unformatted text is considered as a single value of a field
|
|
* named 'Opaque-data'.
|
|
*
|
|
* At the moment the output format is the following (but it may
|
|
* change depending on future requirements so don't count too
|
|
* much on it when writing applications):
|
|
*
|
|
* General: the unformatted text is used as a value of
|
|
* XML output: to be completed
|
|
* Each section is within <response type="object" id="xxx">
|
|
* where xxx is taken from ajaxdest variable or defaults to unknown
|
|
* Each row is reported as an attribute Name="value" of an XML
|
|
* entity named from the variable ajaxobjtype, default to "generic"
|
|
*
|
|
* HTML output:
|
|
* each Name-value pair is output as a single row of a two-column table.
|
|
* Sections (blank lines in the input) are separated by a <HR>
|
