Returns the character class and word-break flags of the character at the specified position. |

Returns TRUE if the character at the specified position is a delimiter; otherwise it returns FALSE. |

Remarks
If wParam is WB_LEFT and WB_RIGHT, the word-break procedure finds word breaks only after delimiters. This matches the functionality of an edit control. If wParam is WB_MOVEWORDLEFT or WB_MOVEWORDRIGHT, the word-break procedure also compares character classes and word-break flags.
For information about character classes and word-break flags, see Word and Line Breaks.
