13 // does not integrate with the runtime's network poller. It cannot
14 // wait for the connection to become writeable, and does not respect
15 // deadlines. If the user-provided callback returns false, the Write
16 // method will fail immediately.
18 // BUG(mikio): On JS, NaCl and Plan 9, the Control, Read and Write
19 // methods of syscall.RawConn are not implemented.
