[zeromq-dev] zconfig question

[Juergen Gnoss]

I've got it finally baked, wasn't that intuitive as I expected, but makes sense.
Thanks Kevin,

Ju

Hi Jürgen,
use zconfig_child and zconfig_next to navigate the config tree. Using zconfig_locate("/geofence/location") you can jump to your first location.

The example for zconfig shows the following



context
    iothreads = 1
    verbose = 1      #   Ask for a trace
main
    type = zqueue    #  ZMQ_DEVICE type
    frontend
        option
            hwm = 1000
            swap = 25000000     #  25MB
        bind = 'inproc:@@//@@addr1'
        bind = 'ipc:@@//@@addr2'
    backend
        bind = inproc:@@//@@addr3

Question: How do I get the second value of the bind key under frontend?


I have a config file where I need to specify several geofence coordinates.
each geofence has a name and an infinite set of vertexes
each vertex has a  lat, long pair

I think to store it like so:


    geofence
        location = 1
            name = "First_Down"
            ll = -11.836177, -77.108178
            ll = -11.836864, -77.108759
            ll = -11.836974, -77.108620
            ll = -11.836271, -77.108046
        location = 2
            name = "First_Up"
            ll = -12.836177, -77.108178
            ll = -12.836864, -77.108759
            ll = -12.836974, -77.108620
            ll = -12.836271, -77.108046
            ll = -12.836864, -77.108759
            ll = -12.836974, -77.108620
            ll = -12.836271, -77.108046

              .
              .
              .
       location = n
            name = "blahblah_Down"
            ll = -13.836177, -77.108178
            ll = -13.836864, -77.108759
            ll = -13.836974, -77.108620
            ll = -13.836271, -77.108046


How do I retrieve that in order to put that in a set of struct's.
I guess using child and sibling is the way to do it, but I'm too stupid to get that right.
Anyone can give me a hint how to get what I want.


thanks
Ju
