Writing hex characters to file

How do I output hexademical values to a file? I would like to include a 00 hex value at the end of a file in my server. What do I need to do in Perl to achieve this?

$number = hex("ffff12c0");

will return the number value of the hex ffff12c0 which is 4,294,906,560

the inverse of this is

printf(lx",$number);

this will print out the hex value of number. so just print your hex value to a file

i.e
$buffer = sprintf("%lx",$number);
print FILEHANDLE $buffer;

will print your hex to the file FILEHANDLE
Or do you mean you want
  print FILEHANDLE "\x00";
?

makerp, it does not mark the end of my file with the '00' hex when I viewed it with my hex editor. Instead, it had set it to '30'...

help?
ozo,

that won't work, cos it would write SCALAR("xxxxxxxx") to the file and that is not what we want
What do you mean by SCALAR("xxxxxxxx")?
ozo,

lets say i set my cgi script to print the date to a file by using print FILEHANDLE &get_date;

then, when i add another print FILEHANDLE \x00(i want to add another 00 hex code after my date) , it would give me this in my file :

15-Mar-2000SCALAR(0x80512cc)
