Synopsis:
    #include <mbstring.h>
    int _ismbccntrl( unsigned int ch );

Description:
    The _ismbccntrl function tests for any multibyte control character.

Returns:
    The _ismbccntrl function returns a non-zero value when the argument is a
    member of this set of characters; otherwise, zero is returned.


Example:
    #include <stdio.h>
    #include <mbctype.h>
    #include <mbstring.h>

    unsigned int chars[] = {
        0x0D,
        '.',
        ' ',
        '1',
        'A',
        0x8140, /* double-byte space */
        0x8143, /* double-byte , */
        0x8254, /* double-byte 5 */
        0x8260, /* double-byte A */
        0x8279, /* double-byte Z */
        0x8281, /* double-byte a */
        0x829A, /* double-byte z */
        0x989F, /* double-byte L2 character */
        0xA6
    };

    #define SIZE sizeof( chars ) / sizeof( unsigned int )

    void main()
      {
        int   i;

        _setmbcp( 932 );
        for( i = 0; i < SIZE; i++ ) {
          printf( "%#6.4x is %sa valid "
                "multibyte control character\n",
                chars[i],
                ( _ismbccntrl( chars[i] ) ) ? "" : "not " );
        }
      }

    produces the following:

    0x000d is a valid multibyte control character
    0x002e is not a valid multibyte control character
    0x0020 is not a valid multibyte control character
    0x0031 is not a valid multibyte control character
    0x0041 is not a valid multibyte control character
    0x8140 is a valid multibyte control character
    0x8143 is a valid multibyte control character
    0x8254 is not a valid multibyte control character
    0x8260 is not a valid multibyte control character
    0x8279 is not a valid multibyte control character
    0x8281 is not a valid multibyte control character
    0x829a is not a valid multibyte control character
    0x989f is not a valid multibyte control character
    0x00a6 is not a valid multibyte control character
