The wmemmove() function copies n wide-characters from the object pointed to by ws2 to the object pointed to by ws1. Copying takes place as if the n wide-characters from the object pointed to by ws2 are first copied into a temporary array of n wide-characters that does not overlap the objects pointed to by ws1 or ws2, and then the n wide-characters from the temporary array are copied into the object pointed to by 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 0, ws1 and ws2 must be a valid pointers, and the function copies zero wide-characters.

The wmemmove() function returns the value of ws1.

No errors are defined.
