wcsspn - advance in a wide-character string, skipping any
of a set of wide characters
SYNOPSIS
#include <wchar.h>
wcsspn (const wchar_t *wcs, const wchar_t *accept);
DESCRIPTION
The wcsspn function is the wide-character equivalent of
the strspn 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 con
tained in the wide-character string accept, or wcslen(wcs)
if there is none.
