NAME
wcsnlen - determine the length of a fixed-size wide-character string
SYNOPSIS
#include <wchar.h>
size_t wcsnlen(const wchar_t *s, size_t maxlen);
DESCRIPTION
The wcsnlen function is the wide-character equivalent of the strnlen function. It returns the number of wide-characters in the string
pointed to by s, not including the terminating L' ' character, but at most maxlen. In doing this, wcsnlen looks only at the first maxlen
wide-characters at s and never beyond s+maxlen.
RETURN VALUE
The wcsnlen function returns wcslen(s), if that is less than maxlen, or maxlen if there is no L' ' character among the first maxlen wide
characters pointed to by s.
CONFORMING TO
This function is a GNU extension.
