/***
* _mbstok - Break string into tokens (MBCS)
*
*Purpose:
*       strtok considers the string to consist of a sequence of zero or more
*       text tokens separated by spans of one or more control chars. the first
*       call, with string specified, returns a pointer to the first char of the
*       first token, and will write a null char into string immediately
*       following the returned token. subsequent calls with zero for the first
*       argument (string) will work thru the string until no tokens remain. the
*       control string may be different from call to call. when no tokens remain
*       in string a NULL pointer is returned. remember the control chars with a
*       bit map, one bit per ascii char. the null char is always a control char.
*
*       MBCS chars supported correctly.
*
*Entry:
*       char *string = string to break into tokens.
*       char *sepset = set of characters to use as seperators
*
*Exit:
*       returns pointer to token, or NULL if no more tokens
*
*Exceptions:
*       Input parameters are validated. Refer to the validation section of the function.
