When set to a value different than
None this should refer to a
function with two integer parameters: an event code and a detail. This
function will be called upon network-generated events such as urgent
data arrival. Macintosh documentation calls this the
asynchronous service routine. In addition, it is called with
MACTCP.PassiveOpenDone when a PassiveOpen()
completes. This is a Python addition to the MacTCP semantics.
It is safe to do further calls from asr.
- PassiveOpen (port)
Wait for an incoming connection on TCP port port (zero makes the
system pick a free port). The call returns immediately, and you should
use wait() to wait for completion. You should not issue any method
calls other than wait(), isdone() or
GetSockName() before the call completes.
- wait ()
Wait for PassiveOpen() to complete.
- isdone ()
1 if a PassiveOpen() has completed.
- GetSockName ()
Return the TCP address of this side of a connection as a 2-tuple
(host, port), both integers.
- ActiveOpen (lport, host, rport)
Open an outgoing connection to TCP address
local port lport (zero makes the system pick a free port). This
call blocks until the connection has been established.
- Send (buf, push, urgent)
Send data buf over the connection. push and urgent
are flags as specified by the TCP standard.
- Rcv (timeout)
Receive data. The call returns when timeout seconds have passed
or when (according to the MacTCP documentation) ``a reasonable amount
of data has been received''. The return value is a 3-tuple
(data, urgent, mark). If urgent data is
Rcv will always return that before looking at any
normal data. The first call returning urgent data will have the
urgent flag set, the last will have the mark flag set.
- Close ()
Tell MacTCP that no more data will be transmitted on this
connection. The call returns when all data has been acknowledged by
the receiving side.
- Abort ()
Forcibly close both sides of a connection, ignoring outstanding data.
- Status ()
Return a TCP status object for this stream giving the current status
