SYNOPSIS
#include <wchar.h>
size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);
DESCRIPTION
The wcscspn() function is the wide-character equivalent of the strc‐
spn() function. It determines the length of the longest initial segment
of wcs which consists entirely of wide-characters not listed in reject.
In other words, it searches for the first occurrence in the wide-char‐
acter string wcs of any of the characters in the wide-character string
reject.
RETURN VALUE
The wcscspn() function returns the number of wide characters in the
longest initial segment of wcs which consists entirely of wide-charac‐
ters not listed in reject. In other words, it returns the position of
the first occurrence in the wide-character string wcs of any of the
characters in the wide-character string reject, or wcslen(wcs) if there
is none.
