SYNOPSIS
#include <wchar.h>
size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);
DESCRIPTION

spn(3) function. It determines the length of the longest initial seg-
ment of wcs which consists entirely of wide-characters not listed in
reject. In other words, it searches for the first occurrence in the
wide-character string wcs of any of the characters in the wide-charac-
ter string reject.
RETURN VALUE
The wcscspn() function returns the number of wide characters in the
longest initial segment of wcs which consists entirely of wide-charac-
ters not listed in reject. In other words, it returns the position of
the first occurrence in the wide-character string wcs of any of the
characters in the wide-character string reject, or wcslen(wcs) if there
is none.
