wcscspn - search a wide-character string for any of a set
of wide characters
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 strcspn 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-character
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-characters 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.
