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.  

CONFORMING TO
