Synopsis:
    #include <mbctype.h>
    int _ismbbalnum( unsigned int ch );

Description:
    The _ismbbalnum function tests if the argument ch satisfies the
    condition that one of  isalnum or  _ismbbkalnum is true.

    Note:  The argument ch must represent a single-byte value (i.e., 0 <= ch
    <= 255 ).  Incorrect results occur if the argument is a double-byte
    character.

Returns:
    The _ismbbalnum function returns a non-zero value if the argument
    satisfies the condition; otherwise a zero value is returned.


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

    unsigned int chars[] = {
        ' ',
        '.',
        '1',
        'A',
        0x8140, /* double-byte space */
        0x8260, /* double-byte A */
        0x82A6, /* double-byte Hiragana */
        0x8342, /* double-byte Katakana */
        0xA1,   /* single-byte Katakana punctuation */
        0xA6,   /* single-byte Katakana alphabetic */
        0xDF,   /* single-byte Katakana alphabetic */
        0xE0A1  /* double-byte Kanji */
    };

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

    void main()
      {
        int   i;

        _setmbcp( 932 );
        for( i = 0; i < SIZE; i++ ) {
          printf( "%#6.4x is %sa single-byte alphanumeric\n"
                  " or Katakana non-punctuation character\n",
                chars[i],
                ( _ismbbalnum( chars[i] ) ) ? "" : "not " );
        }
      }

    produces the following:

    0x0020 is not a single-byte alphanumeric
     or Katakana non-punctuation character
    0x002e is not a single-byte alphanumeric
     or Katakana non-punctuation character
