wchar_t *
wmemmove
(wchar_t *s1, const wchar_t *s2, size_t n);
The function copies the array beginning at s2
to the array beginning at s1
(both of size n
). It returns s1
. If the arrays
overlap, the function accesses each of the element values from s2
before it stores a new value in that element, so the
copy is not corrupted.
