#include <wchar.h>
size_t wcscspn(const wchar_t *ws1, const wchar_t *ws2);
Описание (Description)
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 wcscspn() function shall compute the length (in wide
characters) of the maximum initial segment of the wide-character
string pointed to by ws1 which consists entirely of wide-
character codes not from the wide-character string pointed to by
ws2.
Возвращаемое значение (Return value)
The wcscspn() function shall return the length of the initial
substring of ws1; no return value is reserved to indicate an
error.
