wcspbrk - search a wide-character string for any of a set of wide characters
wchar_t *wcspbrk(const wchar_t *wcs, const wchar_t *accept);
The wcspbrk() function is the wide-character equivalent of the strpbrk(3) function. It searches for the first occurrence in the wide-character string pointed to by wcs of any of the characters in the wide-character string pointed to by accept.
The wcspbrk() function returns a pointer to the first occurrence in wcs of any of the characters listed in accept. If wcs contains none of these characters, NULL is returned.
