+zmq_ctx_shutdown(3)
+==================
+
+
+NAME
+----
+zmq_ctx_shutdown - shutdown a 0MQ context
+
+
+SYNOPSIS
+--------
+*int zmq_ctx_shutdown (void '*context');*
+
+
+DESCRIPTION
+-----------
+The _zmq_ctx_shutdown()_ function shall shutdown the 0MQ context 'context'.
+
+Context shutdown will cause any blocking operations currently in progress on 
+sockets open within 'context' to 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. No further sockets can be created
+using _zmq_socket()_ on a context for which _zmq_ctx_shutdown()_ has been called,
+it will return and set errno to ETERM.
+
+This function is optional, client code is still required to call the linkzmq:zmq_ctx_term[3]
+function to free all resources allocated by zeromq.
+
+
+RETURN VALUE
+------------
+The _zmq_ctx_shutdown()_ 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.
