NAME    [Toc]    [Back]

       wcsnlen - determine the length of a fixed-size wide-character string

SYNOPSIS    [Toc]    [Back]

       #include <wchar.h>

       size_t wcsnlen (const wchar_t *s, size_t maxlen);

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       This function is a GNU extension.
