C extension troubles on windows

ruby-talk

IIRC, sockets on Windows are blocking by default, so without seeing the
code for ETSocketLink() itself, I couldn’t say more.

Non-blocking I/O on Win32 has always been a pain from what I’ve read. I
recommend searching around on the comp.os.ms-windows.programmer.*
newsgroups to see what they have to say on the subject (or the docs on
msdn.com).

Hi ruby extension geeks, and thanks in advance for your help.

The short version of the issue that I am struggling with is
that I have
a native library I created a ruby extension for. The extension works
on linux, but on windows it does not.

I have copies of the library I am extending for both windows
and linux
from our vendor (Spirent). I am using gcc on linux and MSVC.NET on
windows. Everything compiles and links without complaining.

On both windows and linux I am able to successfully execute
the method
“ETGetLibVersion” which gives me back the library version. I
run into
trouble on windows when I try to call “ETSocketLink”. On linux this
call connects and returns as I would expect, however on windows it
connects and blocks. For example when I do a printf before and after
this call I only get output from the first printf and I have to kill
the process to get my cursor back.
