strcspn returns a character position where strpbrk returns a pointer.
Other than that, if no character is found, strpbrk returns a null
pointer; IIRC, under the same circumstances strcspn returns the index
of the NUL at the end of the string (which is rarely useful).

I did post a message to this effect but it doesn't appear to have shown up so here goes again
Just a
_tcspbrk is the equivalent of _tcscspn, but returns a pointer rather than a size_
(both find the first character that IS in a character set from a string

what is the equivalent of _tcsspn that returns a pointer
(that finds the first character that's NOT in a character set from a string

TTBOMK, the standard library doesn't contain such a thing.
