Add cause code information to the channel.

Since
11

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function. The passed in data is copied and so is still owned by the caller.

Parameters
chanThe channel on which to add information
cause_codeThe cause information to be added to the channel
datalenThe total length of the structure since its length is variable
Return values
0on success
-1on error

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function.

Parameters
chanThe channel from which to retrieve information
Return values
