[edit] Definition
INT memcopy ( <VOID POINTER destination> , <VOID POINTER origin> , <INT size> )
Copies a certain number of bytes from one point in memory to another.
[edit] 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. |
[edit] Returns
INT : true
[edit] 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(), memcopy(), say(), free(), array, pointer
