==Definition==
'''INT''' memcopy ( <'''VOID POINTER''' destination> , <'''VOID POINTER''' origin> , '''INT''' size )

Copies a certain number of [[byte]]s from one point in [[memory]] to another.

== Parameters ==
{|
| '''VOID POINTER''' destination || - Pointer to the first byte of the destination.
|-
| '''VOID POINTER''' origin || - Pointer to the first byte of the origin.
|-
| '''INT''' size || - The size of the to be copied memory in bytes.
|}

== Returns ==
'''INT''' : [[true]]

== Example ==
<pre>
Program example;
Const
elements = 10;
End
Private
byte bytearray[elements*2];
byte pointer pbyte;
int i;
End
Begin

// Allocate memory
pbyte = alloc(elements);

// Write numbers to bytes
memset(pbyte,133,elements);

// Copy bytes to bytearray
memcopy(&bytearray[0],pbyte,elements);

// Show numbers
for(i=0; i<elements; i++)
say("byte["+i+"] = " + bytearray[i]);
end

Repeat
frame;
Until(key(_esc))

// Free the used memory
free(pbyte);

End
</pre>
Used in example: [[alloc]](), [[memset]](), [[say]](), [[free]](), [[array]], [[pointer]]
