How to unblock ConnectNamedPipe and ReadFile? [C#]
I have a class (NamedPipeManager) which has a thread (PipeThread) that waits for a NamedPipe connection using (ConnectNamedPipe) and then reads (ReadFile) - these are blocking calls (not-overlapped) - however there comes a point when I want to unblock them - for example when the calling class tries to stop the NamedPipeManager...
How can I interupt it? Using Thread.abort? Thread.interrupt? Is there a proper way to handle this?
Refer to the code below which illustrates my current situation
main()
{
NamedPipeManager np = new NamedPipeManager();
... do stuff ...
... do stuff ...
np.Stop(); // at this point I want to stop waiting on a connection
}
class NamedPipeManager
{
private Thread PipeThread;
public NamedPipeManager
{
PipeThread = new Thread(new ThreadStart(ManagePipes));
PipeThread.IsBackground = true;
PipeThread.Name = "NamedPipe Manager";
PipeThread.Start();
}
private void ManagePipes()
{
handle = CreateNamedPipe(..., PIPE_WAIT, ...);
ConnectNamedPipe(handle, null); // this is the BLOCKING call waiting for client connection
ReadFile(....); // this is the BLOCKING call to readfile after a connection has been established
}
public void Stop()
{
/// This is where I need to do my magic
/// But somehow I need to stop PipeThread
PipeThread.abort(); //?? my gut tells me this is bad
}
};
So, in function Stop() - how would I gracefully unblock the call to ConnectNamedPipe(...) or ReadFile(...)?
Again - asI asked you previously - is there a rule againt doing it?
Most often people on the 2 different forums are not the same, and I get various answers.
So please - if this is a rule let me know - otherwise please explain why this causes you such an issue ...
Over on devshed, where you also target your cross-posting, this is in the "New users - HOW TO POST A QUESTION - READ THIS FIRST" thread.
Apparently you didn't.
