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.
