ZMQ_HEARTBEAT_IVL: Set interval between sending ZMTP heartbeats
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 'ZMQ_HEARTBEAT_IVL' option shall set the interval between sending ZMTP heartbeats
for the specified 'socket'. If this option is set and is greater than 0, then a 'PING'
ZMTP command will be sent every 'ZMQ_HEARTBEAT_IVL' milliseconds.

Option value type:: int
Option value unit:: milliseconds
Default value:: 0
Applicable socket types:: all, when using connection-oriented transports
ZMQ_HEARTBEAT_TIMEOUT: Set timeout for ZMTP heartbeats
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 'ZMQ_HEARTBEAT_TIMEOUT' option shall set how long to wait before timing-out a
connection after sending a 'PING' ZMTP command and not receiving any traffic. This
option is only valid if 'ZMQ_HEARTBEAT_IVL' is also set, and is greater than 0. The
connection will time out if there is no traffic received after sending the 'PING'
command, but the received traffic does not have to be a 'PONG' command - any received
traffic will cancel the timeout.

Option value type:: int
Option value unit:: milliseconds
Default value:: 0
Applicable socket types:: all, when using connection-oriented transports
ZMQ_HEARTBEAT_TTL: Set the TTL value for ZMTP heartbeats
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 'ZMQ_HEARTBEAT_TTL' option shall set the timeout on the remote peer for ZMTP
heartbeats. If this option is greater than 0, the remote side shall time out the
connection if it does not receive any more traffic within the TTL period. This option
does not have any effect if 'ZMQ_HEARTBEAT_IVL' is not set or is 0.

Option value type:: uint16_t
Option value unit:: deciseconds (1/10th of a second)
