ZMQ_TERM(3) 0MQ Manual ZMQ_TERM(3)NAME
zmq_term - terminate 0MQ context
SYNOPSIS
int zmq_term (void *context);
DESCRIPTION
The zmq_term() function shall terminate the 0MQ context context.
Context termination is performed in the following steps:
1. Any blocking operations currently in progress on sockets open within context shall return immediately with an error code of ETERM. With
the exception of zmq_close(), any further operations on sockets open within context shall fail with an error code of ETERM.
2. After interrupting all blocking calls, zmq_term() shall block until the following conditions are satisfied:
o All sockets open within context have been closed with zmq_close().
o For each socket within context, all messages sent by the application with zmq_send() have either been physically transferred to a
network peer, or the socket's linger period set with the ZMQ_LINGER socket option has expired.
For further details regarding socket linger behaviour refer to the ZMQ_LINGER option in zmq_setsockopt(3).
RETURN VALUE
The zmq_term() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
ERRORS
EFAULT
The provided context was invalid.
EINTR
Termination was interrupted by a signal. It can be restarted if needed.

ZMQ_CLOSE(3) 0MQ Manual ZMQ_CLOSE(3)NAME
zmq_close - close 0MQ socket
SYNOPSIS
int zmq_close (void *socket);
DESCRIPTION
The zmq_close() function shall destroy the socket referenced by the socket argument. Any outstanding messages physically received from the
network but not yet received by the application with zmq_recv() shall be discarded. The behaviour for discarding messages sent by the
application with zmq_send() but not yet physically transferred to the network depends on the value of the ZMQ_LINGER socket option for the
specified socket.
Note
The default setting of ZMQ_LINGER does not discard unsent messages; this behaviour may cause the application to block when calling
zmq_term(). For details refer to zmq_setsockopt(3) and zmq_term(3).
RETURN VALUE
The zmq_close() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
ERRORS
ENOTSOCK
The provided socket was invalid.

I'm having trouble with Abnormal Termination errors. What are they, what causes them and how can I prevent them from happening? Are they application specific? (2 Replies)
If I do a netstat -a I can see all the sockets currently open, is there a way that I can tell which application is holding open these sockets ? (3 Replies)
Hi, i am trying to getting the total number of currently open sockets, so i can make an IF statement to see if its over 300 and send a alert.
I looked in this page
docs.oracle.com/cd/E13222_01/wls/docs81/admin_ref/admin_refIX.html
But i didnt find something to get the number of open... (0 Replies)
