File output

[Maxime Petazzoni <maxime.petazzoni@...>]

Hi,

I'm currently programming a little script that need to do byte output to 
a file, but it's not really doing what I want :)

I need to output specific decimal values, such as 0, but I did not find 
out how to it. In fact :

outfile = io.open(filename, "r+b")
outfile:write(0)

outputs the character zero, but not a real zero :

[pts/6] -lua/hills skikda% hexdump -C out
00000000  30                                                |0|
00000001

I also tried with string.format :

outfile:write(string.format("%d", 0))

but it's doing exactly the same.

Do you know how I can do this ?

Thanks,
- Sam
