    Test Suite VSU version 5.0.2
    Test Identification CAPIbase/sigaction 36
    Problem Summary TSD4U.00230 This test may fail due to timing issues on slower systems.
    Problem Text
    This test failure is exposed on slower systems. After the call to
    close() the master side, the master side sends a hangup message to
    the slave side. Even after the close() completes, the hangup message
    from the master side may not have arrived at the slave side to
    generate the signal. When the signalled process's signal handler
    will be called is not predictable. The test makes the assumption
    that as soon as the close() completes, the process's signal handler
    has been called and the flag set. This is an incorrect assumption, as
    system speed and various other factors will determine when the signal
    handler will be called, though the the signal will eventually be
    delivered.
    Test Output
    TEST PURPOSE #36
    After a call to int sigaction(int sig, const struct
    sigaction *act, struct sigaction *oact) with
    SA_SIGINFO set in the sa_flags member of the sigaction
    structure pointed to by act and sig equal to SIGPOLL,
    on entry to the signal catching function specified by
    the sa_sigaction member when a device has disconnected
    the si_code member of the structure pointed to by the
    siginfo argument shall contain POLL_HUP.
    PREP: Open master pseudo tty
    PREP: Determine if pseudo tty is a stream
    PREP: Open slave side of pseudo tty
    PREP: Set up action for SIGPOLL
    PREP: Register for SIGPOLL
    PREP: Generate S_HANGUP SIGPOLL signal
    ERROR: SIGPOLL was not generated
    TEST: si_code field correct
    36 FAIL
