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.
