Format
#include <wchar.h> wchar_t *wmemmove(wchar_t *s1, const wchar_t *s2, size_t n);
Language Level: ANSI 93
wmemmove copies n wide characters from the object
pointed to by s2 to the object pointed to by s1.
Copying takes place as if the n wide characters from
the object pointed to by s2 are first copied into a
temporary array, of n wide characters, that does not
overlap the objects pointed to by s1 or s2.
Then, wmemmove copies the n wide characters from the
temporary array into the object pointed to by s1.
If n has the value 0, wmemmove copies 0 wide characters.
Return Value
wmemmove returns the value of >s1.
Example
This example copies the first five characters in a string to
overlay the
last five characters in the same string. Note that because the
string is only
nine characters long, the source and target overlap.

printf("\nThe string after wmemmove: %ls \n", theString);
return;
