I've been playing with EventMachine, and have a couple of
questions.

1. Francis mentioned "a recent addition which allows
you to respond to 
keyboard input." I haven't found any reference to that
capability. I am 
using eventmachine 0.8.1 .. is that the current version? If
so, please 
point me to the feature that Francis suggested. (I'm
developing in the 
Windows environment.)

2. One thing I need to do is implement a discovery protocol,
involving a 
UDP broadcast. I don't see a way to set SO_BROADCAST on the
underlying 
socket. Is there any way to do that?

Thanks,
Mark Zvilius

sync to the current head revision. There is a file named KEYBOARD that will answer your questions about the keyboard handling.



For UDP broadcasts, just sent the packet to a target address of 255.255.255.255 to get a broadcast on your local lan.

“sync to the
current head revision.&#8221;



 



I’m not
familiar with this process, could you help me get off the ground? What I tried
is copied below. It looks like setup.rb is trying to find <windows.h>, so
I̵7;ll work on getting the right include paths so that it is found, but if
I̵7;m going about this the wrong way please let me know.



 



Thanks!



Mark Z.
