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.
