NAME
       wcsspn - advance in a wide-character string, skipping any of a set of wide characters

SYNOPSIS
       #include <wchar.h>

       wcsspn(const wchar_t *wcs, const wchar_t *accept);

DESCRIPTION
       The wcsspn function is the wide-character equivalent of the strspn function. It 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.
