    Problem Summary TSD4U.00278 putpmsg() on pseudo-terminal returns -1 with errno EBADF
    Problem Text
    The common code to create the STREAMS-based pseudo ttys in
    sreflect.c opens the master tty for read only (O_RDONLY/filedes[0])
    and the slave side for write only (O_WRONLY/filedes[1]).

    This test attempts a write operation from the master side, where
    only read operations are permitted and the operation fails, resulting
    in test failure.

    The error returned by putpmsg call that fails is EBADF, which according
    to CAE specifications for putpmsg, is the error that will be returned
    if "fildes is not a valid file descriptor open for writing", which is
    the case here.
    Test Output
    TEST PURPOSE #39
    A call to ssize_t readv(int fildes, const struct iovec
    *iov, int iovcnt) when fildes refers to a STREAMS file
    and a hangup occurs on the STREAM shall continue to
    operate normally until the STREAM head read queue is
    empty.
    PREP: Create a pipe
    PREP: Determine if pipe is a stream
    INFO: Pipes are STREAMS based on this implementation.
    PREP: Ignore SIGPOLL, SIGHUP, and SIGPIPE signals
    PREP: Set O_NONBLOCK on read end of STREAM
    PREP: Set O_NONBLOCK on write end of STREAM
    PREP: Put some messages on the STREAM
    PREP: Hangup write end of STREAM
    PREP: Sleep for a few seconds
    TEST: readv operates normally until all data is read
    PREP: Open master pseudo tty
    PREP: Determine if pseudo tty is a stream
    PREP: Open slave side of pseudo tty
    PREP: Ignore SIGPOLL, SIGHUP, and SIGPIPE signals
    PREP: Set O_NONBLOCK on read end of STREAM
    PREP: Set O_NONBLOCK on write end of STREAM
    PREP: Put some messages on the STREAM
    ERROR: putpmsg failed, errno = 9(EBADF - Bad file number)
