    Problem Text

    From test output in PIN4U.00057:

    PREP: Create two streams
    PREP: Open master pseudo tty
    PREP: Determine if pseudo tty is a stream
    PREP: Open slave side of pseudo tty
    PREP: Initialize the file descriptors and event structure
    TEST: poll returns correctly when no data has been written
    ERROR: poll returned incorrect value
    Expected 0
    Received 1

    The difference between our test output and the test output in
    PIN4U.00057 is that the submitter used pseudo-terminals and in our
    configuration VSX_TERMIOS_TTY and VSX_TERMIOS_LOOP are not
    pseudo-terminals, therefore the parts of the PREP output dealing
    with pseudo-tty setup is missing.
    Test Output
    ************************************************************************
    /tset/CAPI.os/ioprim/poll/T.poll 12 Failed

    Test Description:
    Base Required Conformance
    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 POLLWRBAND flag is set in the events member and data for a
    priority band greater than 0 which has been written to at least once
    can be written to the file descriptor specified by the fd member
    without blocking and shall set the POLLWRBAND flag in the
    corresponding revents member when found.

    Test Information:
    PREP: Create two streams
    PREP: Initialize the file descriptors and event structure
    TEST: poll returns correctly when no data has been written
    ERROR: poll returned incorrect value
    Expected 0

    Review Recommendation No Resolution Given
    Review Response
    The test output is probably a good enough match that the submitter
    could cite PIN4U.00057. The Open Group's branding administration team
    should decide whether they would allow the submitter to cite
    PIN4U.00057. If not, then a new PIN should be issued.
