<h3>Synopsis</h3>

<tt>#include <string.h></tt><br>

<h3>Description</h3>
|
|
<p>
|
|
The block of memory beginning at <em>src</em>, of length <em>len</em>,
|
|
is copied to <em>dest</em>. <em>dest</em> must point to a region large
|
|
enough to hold it.

|
|
|
|
<p>
|
|
Unlike <A HREF=memcpy.html>memcpy</A>, <tt>memmove</tt> is guaranteed
|
|
to operate correctly if <em>src</em> and <em>dest</em> overlap.
|
|
</p>
|
|
|
|
<h3>Return Values</h3>
|
|
<p>
|
|
<tt>memmove</tt> returns <em>dest</em>.
