size_t wcslen(const wchar_t *ws);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.
The wcslen() function shall compute the number of wide-character codes in the wide-character string to which ws points, not including the terminating null wide-character code.
The wcslen() function shall return the length of ws; no return value is reserved to indicate an error.
No errors are defined.
