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(3) 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.
