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.
