Definition

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

Copies a certain number of bytes 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

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

Used in example: alloc(), memset(), say(), free(), array, pointer
