### rzmq interface

### In general and separate files
# server_context = init.context()
# server_socket = init.socket(server_context, "ZMQ_REP")
# client_context = init.context()
# client_socket = init.socket(client_context, "ZMQ_REQ")
### Server file
# bind.socket(server_socket, "tcp://*:55555")
### Client file
# connect.socket(client_socket, "tcp://localhost:55555")

### For CRAN testing in local (the same process) only to avoid block
cran_context = init.context()
server_socket = init.socket(cran_context, "ZMQ_REP")
client_socket = init.socket(cran_context, "ZMQ_REQ")
### Server
bind.socket(server_socket, "inproc://#1")
### Client
connect.socket(client_socket, "inproc://#1")


### Test rzmq

  send.socket(client_socket, indata)
  c2s <- receive.socket(server_socket)
  stopifnot(all.equal(c2s, indata))

  send.socket(server_socket, "ok")
  s2c <- receive.socket(client_socket)
  stopifnot(all.equal(s2c, "ok"))
