wcscspn(3) Library Functions Manual wcscspn(3)
wcscspn - search a wide-character string for any of a set of wide
characters
Standard C library (libc, -lc)
#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.
For an explanation of the terms used in this section, see
attributes(7).
