Very Computer

Hi,

I have a file on Linux(little Indian m/c) and written
some long integer data in file. Now I get this file on solaris
(Big indian ) m/c (via binary ftp).
How can I get same data which I have entered on linux on
solaris m/c?

Basically I want how to convert little indian m/c file
to big indian m/c file and vice a versa.

Thanks,
Sandeep

You can call me a pedagogue if you like but I won't know what you're on
about!

generally have a look at htonl() ntohl() htons() ntohs().
These are fine if they are use on both sides (before writing something to, or
reading something from a file).
These functions perform no action if they are called on a machine that
already uses the network-format internally.
In your case the file is already there, and you'll have to swap the integers explicitly.

For shorts: swap byte 0 with 1
For longs: swap byte 0 with 3 and byte 1 with 2
For floats: If both machines use IEEE same as long
For doubles: If both machines use IEEE: swap 0 w. 7  1 w. 6  2 w. 5 and 3 w. 4

but this doesn't help much if file contain anything but short ints.

There is also function swab in system library.

And probably, there is perl on your SUN machine. Read man perlfunc about
perl builtins pack and unpack. They can be very helpful in such a
situation. If there is no perl, there can be Tcl with its "binary scan"
and "binary format"
