    Problem Text
    This test may fail on IUTs which return ENOTTY instead of EACCESS.
    ENOTTY is consistent with POSIX tcgetpgrp()/tcsetpgrp() behavior.

    The following is a recent Base resolution concerning error codes
    for tcgetsid. We request a PIN is raised to cover this issue.

    Test Output
    TEST CASE: tcgetsid

    TEST PURPOSE #2
    EACCES in errno and return -1 on a call to pid_t
    tcgetsid(int fildes) when fildes is not associated
    with a controlling terminal.
    PREP: Open master side of pseudo terminal
    PREP: Create session
    PREP: Open slave side of pty as non-controlling terminal
    TEST: tcgetsid returns -1 for slave side
    TEST: tcgetsid placed EACCES in errno
    ERROR: tcgetsid set errno to 25(ENOTTY - Not a typewriter)
    2 FAIL
