Hi,

I have question about named pipes in windows.
Client pipe app should call
WaitNamedPipe and this function waits for named pipe.
Next app calls CreateFile.

I need different solution for waiting for pipe ( if exists).
I need event created by CreateEvent and when event is set it means that named pipe exists and its ready.

Iam trying add named pipes to boost:asio and there is no problem with server named pipe
becouse server call  ConnectNamedPipe and waits for client. Then i get LPOVERLAPPED that asio need.

BOOL WINAPI ConnectNamedPipe(
  __in         HANDLE hNamedPipe,
  __inout_opt  LPOVERLAPPED lpOverlapped
);

I can confirm that WaitNamedPipe returns inmediately if the named piped has not been created yet.

About the overlapped question, could you be more clear?
