wcscspn - search a wide-character string for any of a
set of wide characters
#include <wchar.h>
size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);
The
wcscspn() function is the wide-character equivalent of the strcspn(3)
function.
It determines the length of the longest initial segment 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-character string reject.
The wcscspn()
function returns the number of wide characters in the longest initial segment
of wcs which consists entirely of wide-characters 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.
The
wcscspn() function is thread-safe.
