Add cause code information to the channel.

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

Retrieve a ref-counted cause code information structure.

Since

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function. This function increases the ref count of the returned object, so the calling function must decrease the reference count when it is finished with the object.

Return values
NULLon search failure
Pointerto a ref-counted ast_control_pvt_cause_code object containing the desired information
