FUNCTION
<<wcsnlen>>---get fixed-size wide character string length
INDEX
wcsnlen
ANSI_SYNOPSIS
#include <wchar.h>
size_t wcsnlen(const wchar_t *<[s]>, size_t <[maxlen]>);
TRAD_SYNOPSIS
#include <wchar.h>
size_t wcsnlen(<[s]>, <[maxlen]>)
wchar_t *<[s]>;
size_t <[maxlen]>;
DESCRIPTION
The <<wcsnlen>> function computes the number of wide character codes
in the wide character string pointed to by <[s]> not including the
terminating L'\0' wide character but at most <[maxlen]> wide
characters.
RETURNS
<<wcsnlen>> returns the length of <[s]> if it is less then <[maxlen]>,
or <[maxlen]> if there is no L'\0' wide character in first <[maxlen]>
characters.
PORTABILITY
<<wcsnlen>> is GNU extension..
<<wcsnlen>> requires no supporting OS subroutines.
