zmq_disconnect - Disconnect a socket from an endpoint
|

|
|
SYNOPSIS
|
|
|
|
|
--------
|
|
|
|
|
*int zmq_disconnect (void '*socket', const char '*endpoint');*
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
The _zmq_disconnect()_ function shall disconnect a socket specified
|
|
|
|
|
by the 'socket' argument from the endpoint specified by the 'endpoint'
|
|
|
|
|
argument. Note the actual disconnect system call might occur at a later time.
|
|
|
|
|
|
|
|
|
|
Upon disconnection the will also stop receiving messages originating from
|
2023-08-05 21:31:33 +03:00
|
|
|
this endpoint. Moreover, the socket will no longer be able
|
2021-02-02 19:07:02 +02:00
|
|
|
to queue outgoing messages to this endpoint. The outgoing message queue
|
|
|
|
|
associated with the endpoint will be discarded. However, if the socket's linger
|
|
|
|
|
period is non-zero, libzmq will still attempt to transmit these discarded messages,
|
|
|
|
|
until the linger period expires.
|
|
|
|
|
|
|
|
|
|
The 'endpoint' argument is as described in linkzmq:zmq_connect[3]
|
|
|
|
|
|
|
|
|
|
NOTE: The default setting of _ZMQ_LINGER_ does not discard unsent messages;
|
|
|
|
|
this behaviour may cause the application to block when calling _zmq_ctx_term()_.
|
|
|
|
|
For details refer to linkzmq:zmq_setsockopt[3] and linkzmq:zmq_ctx_term[3].

|
RETURN VALUE
|
|
|
|
|
------------
|
|
|
|
|
The _zmq_disconnect()_ function shall return zero if successful. Otherwise it
|
|
|
|
|
shall return `-1` and set 'errno' to one of the values defined below.
|
|
|
