Copy wide characters from one buffer to another
#include <wchar.h>
wchar_t * wmemmove( wchar_t * ws1,
const wchar_t * ws2,
size_t n );
libc
The memmove() function copies n bytes from the buffer pointed to by ws2 to the buffer pointed to by ws1. This function copies overlapping regions safely.
The wmemmove() function is locale-independent and treats all wchar_t values identically, even if they're null or invalid characters.

Use the wmemcpy() function for greater speed when copying buffers that don't overlap. |
A pointer to the destination buffer ws1.
