Synopsis#

#include <wchar.h>

size_t wcslen(const wchar_t *ws);

Status#

Declared, not implemented

Conformance#

IEEE Std 1003.1-2017

Description#

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 wcsnlen() function shall compute the smallest of the number of wide characters in the array to which ws points, not including any terminating null wide-character code, and the value of maxlen. The wcsnlen() function shall never examine more than the first max-len characters of the wide-character array pointed to by ws.

Return value#

The wcslen() function shall return the length of ws.

The wcsnlen() function shall return the number of wide characters preceding the first null wide-character code in the array to which ws points, if ws contains a null wide-character code within the first max-len wide characters, otherwise, it shall return max-len.

No return values are reserved to indicate an error.
