Pure C implementation of Go channels

“Unbuffered channels provide both a mechanism for communication as well as synchronization. When data is sent into the channel, the sender blocks until a receiver is ready. Likewise, a receiver will block until a sender is ready…”

“Buffered channels accept a limited number of values without a corresponding receiver for those values. Sending data will not block unless the channel is full. Receiving data will block only if the channel is empty…”
