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.
