wcslen - determine the length of a wide-character string

  #include <wchar.h>

  size_t wcslen(const wchar_t *s);

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’).

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

For an explanation of the terms used in this section, see *attributes*(7).

POSIX.1-2001, POSIX.1-2008, C99.

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

*strlen*(3)
