    Problem Summary PIN4U.00044 This test may fail on implementations that do not implement
    STREAMS.
    Problem Text These 3 poll assertions are either modified or new to VSU 4.1.1
    and test streams. The behaviour on our platform is similar to
    PIN4U.00031
    Test Output TEST PURPOSE #2
    A successful call to int poll(struct pollfd fds[],
    nfds_t nfds, int timeout) shall examine each element
    of the fds array for instances where the POLLIN flag
    is set in the events member and data other than
    high-priority data can be read without blocking from
    the file descriptor specified by the fd member and set
    the POLLIN flag in the corresponding revents member
    when found.
    PREP: Create two pipes and a stream
    PREP: Create a pipe
    PREP: Determine if pipe is a stream
    INFO: Pipes are not STREAMs on this implementation
    PREP: Open master pseudo tty
    PREP: Determine if pseudo tty is a stream
    ERROR: Neither pipes nor pseudo terminals are STREAMS
    based on this implementation. The sample code
    in $TET_ROOT/CAPI/SRC/LIB/capi_user/sreflect.c
    must be modified to provide routines with the
    equivalent functionality and interfaces for the
    implementation.

    TEST PURPOSE #34
    A successful call to int poll(struct pollfd fds[],
    nfds_t nfds, int timeout) shall examine each element
    of the fds array for instances where the
    (POLLRDNORM|POLLRDBAND) flags are set in the events
    member and data other than high-priority data can be
    read without blocking from the file descriptor
    specified by the fd member and set the
    (POLLRDNORM|POLLRDBAND) flags in the corresponding
    revents member when found.

    TEST PURPOSE #35
    On a call to int poll(struct pollfd fds[], nfds_t
    nfds, int timeout) when the (POLLRDNORM|POLLRDBAND)
    flags are set for a selected file descriptor which is
    a STREAM with a 0 length non-high-priority message
    available the (POLLRDNORM|POLLRDBAND) flags shall be
    set in the corresponding revents member.

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response A permanent interpretation is recommended.

    The output is consistent with an IUT that does not support STREAMS
    and is similiar to output in PIN4U.00031.

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Permanent Interpretation (PIN)
    Review Conclusion A Permanent Interpretation is granted.
