Similarly to ports, a channel can be passed in a message to another process. The process that posts this operation, however, will loose its access to that channel (channel can link only two threads).

  • tce_chn_rcv
  • tce_chn_set
tce_chn_snd -- sends a message,
  • if required a sending thread will be blocked until the operation completes
