wcsspn

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

       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-char-
       acter 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-charac-
       ters listed in accept.  In other words, it returns the position of the first occurrence in the wide-character string wcs of a  wide-charac-
       ter not contained in the wide-character string accept, or wcslen(wcs) if there is none.
