Usage \cr \code{PAIR} \tab 0L \tab socket type PAIR \cr \code{PUB} \tab 1L
\tab socket type PUB \cr \code{SUB} \tab 2L \tab socket type SUB \cr
\code{REQ} \tab 3L \tab socket type REQ \cr \code{REP} \tab 4L \tab socket
type REP \cr \code{DEALER} \tab 5L \tab socket type DEALER \cr \code{ROUTER}
\tab 6L \tab socket type ROUTER \cr \code{PULL} \tab 7L \tab socket type
PULL \cr \code{PUSH} \tab 8L \tab socket type PUSH \cr \code{XPUB} \tab 9L
\tab socket type XPUB \cr \code{XSUB} \tab 10L \tab socket type XSUB \cr
\code{STREAM} \tab 11L \tab socket type STREAM }

The elements of \code{.pbd_env$ZMQ.SO} are default values for socket
options as defined in `zmq.h' including 60 different values, see
\code{.pbd_env$ZMQ.SO} and `zmq.h' for details.

The elements of \code{.pbd_env$ZMQ.SR} are default values for send/recv
options as defined in `zmq.h' including \tabular{lcl}{ Elements \tab Value

send/recv option SNDMORE (not supported) }

The elements of \code{.pbd_env$ZMQ.MC} are default values for warning and
stop controls in R. These are not the ZeroMQ's internal default values. They
