Copy a wide-character string, to a maximum length
#include <wchar.h>
wchar_t * wcsncpy( wchar_t * ws1,
const char * ws2,
size_t n );
libc
The wcsncpy() function copies the string pointed to by ws2, including the terminating NUL wide character, into the array pointed to by ws1, to a maximum of n wide characters. It adds NUL characters if ws2 has fewer than n characters but doesn't add a NUL if ws2 has more.

This function isn't guaranteed to work properly for copying overlapping strings; use wmemmove() instead. |
The same pointer as ws1.
