problem with fwrite

Hi,

I'm trying to output raw dwords to a file but if the dword contains the byte 0x0A then it is being treated as end of line and a CR 0x0D is being inserted.

i.e.

Code:


format PE console
entry start

include '%fasminc%\win32a.inc'

section '.text' code readable executable

    start:
        cinvoke fopen, fileName, fileWrite
        mov     [fileHnd], eax
        mov     [num], 0x00030AF3
        cinvoke fwrite, num, 4, 1, [fileHnd]
        cinvoke fclose, [fileHnd]
        invoke ExitProcess, 0

;**************************************************************************************************
section '.data' data readable writeable

fileWrite       db "w", 00
fileName        db "tmp.dat", 00
fileHnd         dd ?
num             dd ?

;**************************************************************************************************
section '.idata' import data readable writeable

library msvcrt, 'msvcrt.dll',\
        kernel32, 'kernel32.dll'

import  msvcrt,\
        fopen, 'fopen',\
        fclose, 'fclose',\
        fwrite, 'fwrite'

include '%fasminc%\api\Kernel32.inc'

I want the above to produce a 4-byte file containing F3 0A 03 00
but I get a 5-byte file with F3 0D 0A 03 00

How can I get the output I want ?

Thanks
