Endian-ness [message #29236]

Is there a system variable that gives the endian-ness of the current
hardware? I am reading a file which tells me the endian-ness of the
data, and I'd like to swap_endian if it is different from the current
hardware. In lieu of finding a system variable to compare to, I have
done this:

test_int = 1
byteorder,test_int,/ntohs
big_endian = test_int eq 1

"network" byte order is big-endian, so I convert a 1 to the host
byte-order and see if it's still a 1.

This way works fine, but it seems as thought I'm missing something.
Is there a better way? Using the byteorder routine to convert the data
is not an option (unless it's been improved for 5.5).

Thanks.
