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

NAME         top

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

SYNOPSIS         top

       #include <wchar.h>

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

DESCRIPTION         top

       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         top

       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.
