    Problem Text
    This test may fail on IUTs with no STREAMS devices.

    Based on a working group resolution (initial tracking number was
    req.4.U.00059) no STREAM file descriptors need exist. The code
    in $TET_ROOT/CAPI/SRC/LIB/capi_user/sreflect.c is sample code
    which contains functions to:

    int stream_reflector_fildes(int fildes[2])
    Setup two STREAMS devices in a "loopback" configuration
    opening both devices and returning file descriptors for them.

    char *stream_reflector_name(int *fildes)
    Setup two STREAMS devices in a "loopback" configuration
    opening one device and returning a file descriptor for it
    and not opening the other end and returning a name for it
    which can be opened later.

    void stream_reflector_cleanup(void)
    Free resources used by stream_reflector_fildes() or
    stream_reflector_name().

    We have not modified these routines because they could not be used.
    Based on the working group decision we do not provide STREAMS devices.

    Therefore we request that a permanent interpretation be granted
    for these assertions based on this resolution since they would
    require that stream file descriptors be supported on our
    implementation in order to pass.

    Review Recommendation No Resolution Given
    Review Response
    req.4.U.00059 contends that STREAMS are not required. We argued
    that they were. The issue went for review, and was discussed at
    the November 95 BWG meeting, The BWG felt unable to decide and
    referred the matter back to X/Open. X/Open eventually refused
    req.4.U.00059 as PG4U.00038.

    We still recommend this request be refused as per our response in
    PG4U.00038.

    However, this issue was raised again at the February 96 working group
    meeting. The minutes state that

    After some discussion, it was agreed that this issues arises from
    a deficiency in the specification, in that it fails to clearly
    indicate that implementation should implement at least one
    STREAMS device. The group agreed that "none" should be an
    acceptable answer to question 17 in the CSQ ("What networking
    services or other character-based device types are implemented
    using STREAMS?"). The deficiency in the specification will be
    fixed in the next release. This decision is recorded in
    Resolution 96-2-5.

    This may affect X/Open's final decision.
