Re: Nim zmq binding and poll function

[Araq]

Something like this:
    
    
    type
      TPollItem* = object
        socket*: PSocket
        fd*: cint
        events*: cshort
        revents*: cshort
        poller*: pointer
    
    proc poll*(items: ptr UncheckedArray[TPollItem], nitems: cint, timeout: 
clong): cint{.
      cdecl, importc: "zmq_poll", dynlib: zmqdll.}
    
    template asUncheckedArray(a): untyped = cast[ptr 
UncheckedArray[typeof(a[0])]](addr a[0])
    
    var a: array[2, TPollItem]
    a[0] = TPollItem(socket: d1.s, events: ZMQ_POLLIN)
    a[1] = TPollItem(socket: d2.s, events: ZMQ_POLLIN)
    
    # Poll on 2 element starting at adress p1
    var res : int = poll(asUncheckedArray(a), 2, 10000)
    echo res
    if res >= 0 :
        var res1 = bitand(p1.revents, ZMQ_POLLIN.cshort)
        var res2 = bitand(p2.revents, ZMQ_POLLIN.cshort)
        echo "res1:", res1, " && res2:", res2
