    Problem Text

    According to the X/Open CAE issue 4 version 2 section 5.3 line 1984-1985,
    it states:

    print Define characters to be classified as printable characters,
    including the space character.

    According to the X/Open CAE issue 4:

    int isprint(int c);
    The isprint() function returns non-zero if c is a printing character.

    int iswprint (wint_t wc);
    The iswprint() function returns non-zero if wc is a printing wide-character.

    The iswctype() function returns non-zero for true.

    Since 0x20, the space character is considered as a printable character,
    the test should expect non-zero not zero as the return value.
    Test Output



    ************************************************************************
    /tset/ANSI.os/charhandle/isprint/T.isprint 1 Failed

    Test Description:
    isprint() returns non-zero if and only if the character is a printing
    character in the character classification table associated with the
    current locale specified in LC_CTYPE.
    Posix Ref: Component ISPRINT Assertion 8.1-04(A)

    Test Strategy:
    CREATE child process
    (child) FOR locales VSX4L1 and VSX4L2 :
    FOR categories LC_ALL and LC_CTYPE :
    FOR all ASCII values :
    VERIFY value returned by isprint() against expected value

    /tset/XPG4.os/wcharhandle/iswctype/T.iswctype 2 Failed

    Test Description:
    When the wide character c is defined to not have property property in
    the wide character classification table associated with the current
    locale specified in LC_CTYPE, then a call to iswctype() returns zero.

    Test Strategy:
    OBTAIN multibyte strings using wcharcfg()
    CHILD process:
    CHANGE to test locale using setlocale()
    FOR each valid property name, call wctype()
    VERIFY that return value from wctype() when used as the second
    argument to iswctype(), with character argument not with that
    property returns zero.

    Test Information:
    With locale set to VSX4L1
    iswctype( , wctype(print)) returned 128, expected zero
    With locale set to VSX4L2
    iswctype( , wctype(print)) returned 128, expected zero

    VERIFY value returned by iswprint() is zero
    FOR both wide-character locales :
    FOR category LC_CTYPE :
    FOR non-printing wide-character values :
    VERIFY value returned by iswprint() is zero

    Test Information:
