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 ?
