The wcspbrk() function shall locate the first occurrence in the wide-character string pointed to by ws1 of any wide-character code from the wide-character string pointed to by ws2.
Upon successful completion, wcspbrk() shall return a pointer to the wide-character code or a null pointer if no wide-character code from ws2 occurs in ws1.
No errors are defined.
