Help with named pipes

[Zaph-0]

Hi,

I start a named pipe in a server process:

pipe = CreateNamedPipe("\\\\.\\pipe\\Test", PIPE_ACCESS_DUPLEX | FILE_FLAG_WRITE_THROUGH, PIPE_TYPE_BYTE, PIPE_UNLIMITED_INSTANCES, 1000, 1000, 3000, NULL);


and use it in a client with:


pipe = CreateFile( "\\\\.\\pipe\\Test", GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
WriteFile(pipe, buffer, 7, (DWORD*)&y, NULL);
CloseHandle(pipe);

I receive the data on the server side but the problem is that i cannot open the pipe from the client again. I always get an error.

Is there something that I am missing ?

I really appreciate any help on this.

I always get an error.

Well...what error?

• A SDK function (e.g. CreateDirectory) failed. What I'm doing wrong?

Are you doing the CreateFile(...) again?

Is there a reason why you're closing the pipe immediately after doing the Write??
