    Problem Summary PG4U.00125 This request claims that the rename() call in the test setup is not portable and is failing.
    Problem Text
    This test is dependent upon being able to write (rename) in /dev.
    The spec refers only to reading from /dev ....and whether or not
    writing is allowed is implementation specific.
    Test Output
    TEST CASE: ptsname

    TEST PURPOSE #3
    A call to char *ptsname(int fildes) when the slave
    device name does not exist in the file system shall
    return NULL.
    PREP: Open master pseudo terminal
    PREP: Get slave pseuc=do terminal
    PREP: Unlock slave device
    PREP: Get name of pseudo terminal device
    PREP: Rename /dev/pts/3 to /dev/pts/3.save
    TEST: ptsname returns NULL
    ERROR: ptsname returned /dev/pts/3
    CLEANUP: Rename /dev/pts/3.save to /dev/pts/3
    3 FAIL

    Review Recommendation No Resolution Given
    Review Response
    We recommend this request be refused.

    If the rename() call in the test setup was failing the test output
    above should show an error after the line

    PREP: Rename /dev/pts/3 to /dev/pts/3.save

    and the test should fail with an UNRESOLVED result. Since this is
    not happening we believe the rename succeeds in removing (renaming)
    the slave device name.

    According to the spec

    Upon failure, ptsname() returns a null pointer. This could occur
    if fildes is an invalid file descriptor or if the slave device
    name does not exist in the file system.

    Since the slave device has been renamed and no longer exists we
    believe the IUT should be returning NULL.
