Re: how to find Endianness on HP

Hi Madhava,

I found this (C code):

===============================
#include
int endian;

TEST_ENDIAN(endian);

if (endian == 0)
printf("This a little endian system\n");

if (endian == 1)
printf("This a big endian system\n");
===============================

here:

HTH!

Hope this helps!
Regards
Torsten.

HP-UX and Solaris are big endian operating systems.

Linux and Windows are little endian.

Re: how to find Endianness on HP

It is big-endian. However you can change it to little endian.

Newer PA-RISC computers can be either big endian or little endian machines, however the HP-UX operating system is a big endian operating system.

Refer: http://docs.hp.com/en/5990-8172/ch02s10.html The Endian Difference Problem part

You can find endian type with gdb as,

# gdb -q
gdb)show endian
gdb)q
#

hth.
Easy to suggest when don't know about the problem!
