a set of wide characters
Synopsis
#include <wchar.h>
size_t wcscspn( |
const wchar_t * |
wcs, |
| |
const wchar_t * |
reject); |
DESCRIPTION
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.
RETURN VALUE
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.
