[snip] > Thanks. This runs fine with the current HEAD of topic/fifo. We are very grateful for your efforts The test-program works fine now with the latest commits in topic/fifo There are some (possible other) issues that make our application doesn't work as in Linux and we haven't had the time to dig into what the problems are yet. A quick guess is that it is related to signals and possible related to pselect, but we need to dig deeper into the logic to narrow down the problems. Shall we "close" this issue even if we find out that there's still problems with "named pipes" later on ? The application server (the open source project) that we're trying to make work in Windows can be found here https://bitbucket.org/casualcore/ (if interested) Once again, tnx Ken Kristian > Ken
