    Test Identification CAPIbase/readv 70
    Problem Summary TSD4U.00238 This test needs to set the size of the file before it reads from it.
    Problem Text
    There are multiple problems with this test, two of which have been
    addressed by TSD4U.00225 (on systems that don't support the 64-bit
    compilation environment) and TSD4U.00222 (on systems that support a
    64-bit compilation environment but not a 64-bit execution environment).
    Note that because of the problem noted in TSD4U.00225 (makefile test
    for "unsupported" rather than "undefined" for getconf options), this
    test is also wrongly testing the unsupported XBS5_LP64_OFF64
    and XBS5_LPBIG_OFFBIG environments on the system under test. However,
    the test continues because as per XSH5, XBS5_ILP64_OFF64_CFLAGS
    and XBS5_LPBIG_OFFBIG_CFLAGS are still valid options to getconf
    though we return the null string for each in this case. This results
    in make creating default 32-bit, off32 binaries, when the test is
    expecting LP64_OFF64 and LPBIG_OFFBIG binaries.

    Once we can get by the failures noted above, we are left with the remaining
    failure with readv() which is occuring in the valid 32-bit tests as well:

    ERROR: In LFS program: readv() did not fail as expected. Expected:
    -1 Recevied:

    This failure is the result of an error in the test. The test attempts
    to read past a small off_t file's limit expecting the read to fail. The
    read does not fail however, because the file has no size or data. Hence
    the readv() statement returns 0 because there is no data to read. This
    test functions properly if it is updated such that the created file has
    data or a size established so there is something to read. update, the
    test functions correctly.
    Test Output
    TEST CASE: readv

    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.
