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.
