    Test Identification CAPIsockets/send 27
    Problem Summary TSD4U.00272 This test may fail (if datagram sockets cannot be filled on the implementation).
    Problem Text
    This IR is for the following tests:

    Sockets: send 27
    Sockets: sendto 44
    Sockets: sendmsg 46

    These tests are supposed to fill up the send socket and then test that send()
    blocks. However, on our implementation the send socket never gets full. In
    these tests both sockets are datagram sockets. It is common practice (reference:
    TCP/IP, Illustrated Vol2) to pass the message immediately to the protocol
    where it is queued for transmission on the the appropriate network device.
    This in effect means no data is stored in the send buffer directly. These
    tests send messages that are not greater than the maximum buffer size and
    thus get sent directly to the protocol layer.

    Note; that there is an error in these tests, the following line is incorrect.

    sprintf(ebuf, " Expected -1 %d Received: %d\n", ret);

    The first "%d" should be deleted.
    Test Output
    TEST CASE: send

    TEST PURPOSE #27
    If the implementation supports a communications domain
    and a socket type and allows the option to be set:
    The SO_SNDTIMEO option shall define the amount of time
    to block because flow control prevents data from
    being sent for a call to ssize_t send(int socket,
    const void *buffer, size_t length, int flags).

    Review Response
    For send 27 and sendto 44:

    We agree this is a test suite deficiency in the test suite versions listed.

    For sendmsg 46:

    This appears to be an unrelated failure - it is occurring on a stream
    socket and at a different point in the test. We beleive this is an
    implementation issue and this waiver does NOT apply to sendmsg 46.

    Review Conclusion
    This is an agreed Test Suite Deficiency. This TSD applies to
    send 27 and sendto 44 tests only.
