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.
