Does Ruby support Asyncronous Sockets on Win32

The Programming Ruby book lists
IO.fcntl() as not supported on all platforms.

Does cygwin vs. non cygwin make a difference.

And if it’s supported, does
sysread() return 0 when the client disconnects.

These flags are supported in MS VC build of Ruby:

irb(main):001:0> require ‘fcntl’
true
irb(main):002:0> Fcntl.constants
[“O_APPEND”, “O_WRONLY”, “O_TRUNC”, “O_RDWR”, “O_EXCL”, “O_RDONLY”,
“O_CREAT”]
irb(main):003:0>

As you can see there is no flag for nonblocking IO.

I believe so but I did not test the cygwin version.

And if it’s supported, does
sysread() return 0 when the client disconnects.

Does not work for me with MS VC build and WinXP. sysread is blocked like
anything else.
