|---|---|---|
| duplex | bool | If duplex is True (the default) then the pipe is bidirectional. If duplex is False then the pipe is unidirectional: conn1 can only be used for receiving messages and conn2 can only be used for sending messages. |
| conn1_nonblock | bool | If conn1_nonblock is True then the connection1 is non-blocking |
| conn2_nonblock | bool | If conn2_nonblock is True then the connection2 is non-blocking |
