#include <wchar.h> wchar_t *wcspbrk(const wchar_t *ws1, const wchar_t *ws2);
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.
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.
