WCSPBRK(3) Linux Programmers Manual WCSPBRK(3)
wcspbrk - search a wide-character string for any of a set of wide char
wchar_t *wcspbrk(const wchar_t *wcs, const wchar_t *accept);
The wcspbrk() function is the wide-character equivalent of the strp
brk(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.
