BUG: Setting a Receive Timeout on a Raw Socket Has No Effect

• Microsoft Win32 Application Programming Interface (API) included with: - Microsoft Windows NT version 4.0

SYMPTOMS

When you set a receive timeout on a raw socket, a blocking receive call posted on that socket (which is supposed to timeout if no data is received) blocks indefinitely.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The following code segment is normally used to make a receive call timeout if no data is received within a given period of time:

   SOCKET socket;
   int timeout = 1000;   // Desired timeout in milliseconds

   retval = setsockopt (socket,
                        SOL_SOCKET,
                        SO_RCVTIMEO,
                        (char*)&timeout,
                        sizeof(timeout));
