Re: Running Selector on device file in linux. How to get file descriptor (int fd) from file object?

[cblake]

Well, to make it work without the rest of your type environment, I changed just 
the first couple lines of your posted code to: 
    
    
    import posix, selectors
    proc readDevice(dev: string) =
      let devfd = posix.open(dev, posix.O_RDWR)
    
    
    Run

Then it compiled fine for me. I usually run a pretty fresh devel version of 
Nim. You may be on some earlier Nim. It's probably more useful long-term for 
you to learn to install a devel version of Nim than for me to test on 
back-dated versions.
