Re: [ts-7000] size and byte order of ints

["Don W. Carr" <>]

If you are writing C/C++ code, you should always use these functions:


htonl, htons, ntohl, ntohs

On machines that do not need to switch the bytes, they do nothing. 

See here for a long discussion, and even a program to determine if a system is big-endian or little-endian

http://www.answers.com/topic/endianness

On the question of 64 bit integers, does anybody know if there is a standard routine to convert to network byte order?

Anyone know off-hand where I can find a reference to the length of
various ints on the arm chip?

I need to allocate 16, 32, and 64 unsigned ints, and I don't know if
such animals exist on the arm....

Also, I've read that the arm can be both big-endian and little-endian.
How does one go about determining which variant we have? Or is it
software-set?
