Copy wide-characters in memory.
Standard library (libc.a)
#include <wchar.h>
wchar_t *wmemcpy (wchar_t * ws1, const wchar_t * ws2, size_t n) ;
The wmemcpy function copies n wide-characters from the object pointed to by ws2 to the object pointed to be ws1. This function is not affected by locale and all wchar_t values are treated identically. The null wide-character and wchar_t values not corresponding to valid characters are not treated specially.
If n is zero, ws1 and ws2 must be a valid pointers, and the function copies zero wide-characters.
The wmemcpy function returns the value of ws1.
