Subject: [PATCH] Problem: The documentation for zmq_poller_new incorrectly
 states that it cannot fail.

Solution: Revise the offending wording, adding a remark that zmq_poller_new will return NULL in case of failure.

Fixes #3425.

 RETURN VALUE
 ------------
-_zmq_poller_new_ always returns a valid pointer to a poller.
+_zmq_poller_new_ returns a valid pointer to a poller, or NULL in case of a failure.
 
 All functions that return an int, return -1 in case of a failure. In that case,
 zmq_errno() can be used to query the type of the error as described below.
