/***
|
|
* _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 nullptr 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 nullptr if no more tokens
|
|
*
|
|
*Exceptions:
|
|
* Input parameters are validated. Refer to the validation section of the function.
