64-bit numbers

I don't know what why is this not working.

I get this:
valseq = {129,238,123,1,0,0,0,0}
val = 0.000000

Code:

atom ptr, val
sequence valseq

--Allocate
ptr = allocate (8)

-- Here I send message to C program which will
-- write into ptr.
....

-- Read what C program has written into our buffer:
valseq = peek ({ptr, 8})
val = float64_to_atom (valseq)



// C code which writes into
// buffer which was allocated in Euphoria program.
LONGLONG llPlayback; //64-bit value
int address_data_size = 8;
llPlayback = 24899201;
WriteProcessMemory(
          hCallerProcess,
         (LPVOID) address,
          &llPlayback,
          address_data_size,
          &bytesWritten);


Maybe I should divide 64-bit number into two 32-bit numbers. How would I do
that? In Euphoria or C.
