Description

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’\0’ 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’\0’ character among the first maxlen wide characters pointed to by s.

"CONFORMING TO"

This function is a GNU extension.
