    Problem Text

    Depending on the strxfrm maximum expansion factor, strxfrm() can use an
    unknown amount of space for the transformed value.

    Either the test set-up should contain a way to specify the "strxfrm()
    maximum expansion factor" (in our case it would be 8-to-1) or the program
    should keep trying bigger and bigger buffer sizes until the result fits
    entirely in the buffer.

    The test may use 25 as n, but it should expect the first 25 bytes are there,
    instead of the entire result. It should keep enlarging the buffer until the
    returned count is smaller than the buffer size.

    Test Output


    /tset/XPG4.os/wstring/wcsxfrm/T.wcsxfrm 2 Failed

    Test Description:
    If wcsxfrm() is supported:
    A call to wcsxfrm() transforms the wide string pointed to by s2
    into the wide character array pointed to by s1 taking account of
    the language dependent collating information defined for the
    current locale value for the LC_COLLATE category.
    The resulting wide string s1 is such that the wide string will be
    correctly ordered against another transformed wide string for the
    specified language collating sequence using the function wcscmp().
    The result of this wcscmp() corresponds to the result of a
    wcscoll() on the original strings.
    Otherwise:
    A call to wcsxfrm() returns (size_t)-1 and sets errno to ENOSYS.

    Test Strategy:
    FOR locale SET to VSX4L1 and VSX4L2
    VERIFY collation of accented characters in correct order
    VERIFY that strings with different primary order collate in primary
    order sequence even though secondary ordering differs
    VERIFY collation of accented characters against non-accented
    characters
    VERIFY collation of dictionary orderings (upper/lower case)
    VERIFY that don't care characters are ignored.
    SET locale to other language
    VERIFY collating sequence is for current language
