Linux 2.6 - man page for wcsspn (linux section 3)

WCSSPN(3)			    Linux Programmer's Manual				WCSSPN(3)

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

       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.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wcsspn() function is thread-safe.
