Subject: 64 bits integer - ERRATA
Date: Wed, 10 Nov 2004 00:31:20 -0300	[thread overview]
Message-ID: <41918B88.3060807@ig.com.br> (raw)

Excuse me, when I say "64 bits", I m assuming that the OS are running 
under a processor with 32 bits only,  where "long" type ll have only 32 
bits and "double" could has 64 bits, but it isn't a integer, in other 
hands, I couldn't convert a double to a text string assuming that it is 
integer with a function like printf().

Then, retrying the question:
Does exist a way or some system call or another thing in Linux that 
allow us to manipulate integer values larger than a system DWORD (long) ?
Samples:
- int64, atoi64(), i64toa(), ...
- int128, atoi128(), i128toa(), ...

How can we do to manipulate integer higher than 32 bits in linux ?

Does exist some system call (or another library), that allow us to do 
something like as following ?

int64 x;
x = atoi64("12345678901234567890");

char x[21];
i64toa(x, sizeof(x));

Thanks,

Luciano
