Re: how to get value of object's field from second thread?

[r3d9u11]

How to do it correctly and, probably, elegantly? (sorry, but constructions like 
[this](https://forum.nim-lang.org/t/1572/2#9868) looks a bit mad for this easy 
task  I tried something like a: 
    
    
    import os, threadpool
    
    type
      MyObj = object
        flag: bool
    
    proc subThr(pObj: ptr MyObj) {.gcsafe.} =
      pObj.flag = true
    
    var pShr = cast[ptr MyObj](allocShared0(sizeof(MyObj)))
    
    var o: MyObj = pShr[]
    o.flag = false
    spawn subThr(pShr)
    sleep 100
    echo o.flag
    

But it's don't write data by pointer. Maybe somebody have ideas?
