So you are suggesting that with the proper header files and a little
fiddling I could build and run a Visual Studio.Net project on top of the
cygwin DLL and use additional Cygwin libraries in it? That is what it
sounds like to me. As an application programmer, I don't look under the
hood. I leave that to the kernel programmers that understand the
intricacies involved. I already have enough trouble debugging some
hardware vendors' libraries.
I have attempted to go the other way, with no success. I tried to use
Cygwin B.20 to write some MS-Windows services a few years ago. One was a
simple TCP/IP socket proxy, and I never could get it to talk with the
Service Control Manager. It took about two hours to get it running as a
daemon on Slackware and half a day to port it into MSVC6.
