    Problem Text

    These are slightly different instances of the failures described in
    TSD4U.00238 and TSD4U.00239. The argument for test case #71 parallels
    that for #70 and #72.

    Test Output

    TEST PURPOSE #70
    If the implementation allows creation of a file
    description with an offset maximum less than the
    largest size it supports for an off_t:
    On a call to ssize_t readv(int fildes, const struct
    iovec *iov, int iovcnt) for a regular file data
    transfer shall not occur past the offset maximum
    established in the open file description associated
    with fildes.

    TEST PURPOSE #71
    If the implementation allows creation of a file
    description with an offset maximum less than the
    largest size it supports for an off_t:
    EOVERFLOW in errno and return -1 on a call to ssize_t
    readv(int fildes, const struct iovec *iov, int iovcnt)

    zero, the starting position is before the end of file,

    We recommend this request be refused.

    VSU5.0.3 provides a workaround for these failures. We recommend
    that the implementation be required to apply this patch prior to
    making a single branding run.
