NAME

       wcslen - determine the length of a wide-character string

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <wchar.h>

       size_t wcslen(const wchar_t *s);

DESCRIPTION

       The  wcslen()  function  is  the  wide-character equivalent of the strlen(3) function.  It
       determines the length of  the  wide-character  string  pointed  to  by  s,  excluding  the
       terminating null wide character (L'\0').

RETURN VALUE

       The wcslen() function returns the number of wide characters in s.

NOTES

       In  cases  where  the  input  buffer  may  not  contain a terminating null wide character,
       wcsnlen(3) should be used instead.
