Linux behavior), or the interface may not be implemented on Linux.
wmemcpy - copy wide characters in memory
wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
The wmemcpy() function shall copy n wide characters from the object pointed to by ws2 to
the object pointed to by ws1. This function shall not be affected by locale and all
wchar_t values shall be treated identically. The null wide character and wchar_t values
not corresponding to valid characters shall not be treated specially.
If n is zero, the application shall ensure that ws1 and ws2 are valid pointers, and the
function shall copy zero wide characters.
The wmemcpy() function shall return the value of ws1.
No errors are defined.
