SYNOPSIS
#include <wchar.h>
size_t wcsspn(const wchar_t *wcs, const wchar_t *accept);

determines the length of the longest initial segment of wcs which consists entirely of
wide-characters listed in accept. In other words, it searches for the first occurrence in
the wide-character string wcs of a wide-character not contained in the wide-character
string accept.
RETURN VALUE
The wcsspn() function returns the number of wide characters in the longest initial segment
of wcs which consists entirely of wide-characters listed in accept. In other words, it
returns the position of the first occurrence in the wide-character string wcs of a wide-
character not contained in the wide-character string accept, or wcslen(wcs) if there is
none.
