Adds a VortexChannel into an existing VortexConnection.
The channel to be added must not exists inside connection, otherwise an error will be produced and channel will not be added.
This function only adds the data structure which represents a channel. It doesn't make any work about beep channel starting or something similar.
Mainly, this function is only useful for internal vortex library purposes.
|connection ||the connection where channel will be added. |
