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

SYNOPSIS
       #include <wchar.h>

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

DESCRIPTION
       The wcsspn() function is the wide-character equivalent of the strspn(3)
       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.
