I take this to mean a CYGWIN app is on one end and a native app on the other. Remember the test case ? When it hangs can you remember who was reading and who was writing. Is there a native standard app in Win2k/XP that can be used ? In MSDN there is: "The pipe server should not perform a blocking read operation until the pipe client has started. Otherwise, a race condition can occur. This typically occurs when initialization code, such as the C run-time, needs to lock and examine inherited handles." Could this be related ? Does anyone on the list know the background of the statement, it sounds like a Windows documented bug/feature. How is the notion of Server or Client end given when both ends are only using Open/Read/Write and never using CallNamedPipe, ConnectNamedPipe, WaitNamedPipe. Is the creator automatically the server ?
