<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Either way works. It's really a matter of personal taste. Paul's method is used more often in Asterisk, but I don't believe there's a specific coding guideline enforcing it.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Okay, I was interested in Russells comment 'this function leaks a channel reference'. But also noticed the syntax was used quite often within other modules. I just trying to understand why.
You do raise a good point, I was considering creating a wiki page documenting the coding guidelines to create a manager event. More for a learning experience.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch allows for setting variables on a group of channels.
First a channel is assigned a group via dialplan GROUP() or GroupSet via the ami (new command)
Then, variables can be set on that group with the GROUP_VAR() dialplan function, or GroupVarSet in the manager
This patch also adds manager events for channel group changes, and variable updates
When a group is no longer used (all channels referencing the group are hung up, or all channels referencing the group have their group changed/unset), variables are destroyed
new manager commands:
GroupSet - adds functionality to the manager to be able to set a GROUP() on a channel.
GroupsShowChannels - show each channel and it's associated groups (a channel will be repeated for each group@category it's a member of)
GroupsShowVariables - show variables in each group@category, one event per group, all variables are contained in each group@category event
GroupVarSet - set a group variable (the group has to exist)
GroupVarGet - get a group variable
new manager events:
GroupCreate
GroupChannelAdd
GroupChannelRemove
GroupDestroy
GroupVarSet
Example AMI:
Action: GroupVarSet
Group: 1000
Category: ConferenceBridge
Variable: LastUpdateCheck
Value: 1263502512
Example CLI:
demo1*CLI> group show variables
Group Variables Category
1000 ConferenceBridge
LastUpdateCheck=1263502512
1000 ConferenceModerator
2 active groups
Adds support for:
Group variables
dialplan access: GROUP_VAR()
cli access: group show variables
manager access: GroupVarSet GroupVarGet
Group information:
manager access: GroupSet GroupsShow GroupsShowChannels GroupsShowVariables
