Hi Ed,

thanks for the reply. The help says that Win95/98 cannot create
named pipes but can open existing ones via CreateFile().

I figured it out and the problem is that the default security
descriptor is too restrictive.
If anyone interested I found this code on the web that shows how
to create a security descriptor with all access to the pipe:

   static SECURITY_DESCRIPTOR sd;
   static SECURITY_ATTRIBUTES sa;
   static bool sdInited = false;

   if (!sdInited)
   {
      InitializeSecurityDescriptor (&sd, SECURITY_DESCRIPTOR_REVISION);
      SetSecurityDescriptorDacl (&sd, TRUE, (PACL) NULL, FALSE);
      sa.nLength = sizeof (sa);
      sa.lpSecurityDescriptor = &sd;
      sa.bInheritHandle = false;
      sdInited = true;
   }

   //pass sa to CreateNamedPipe...
