Does Ada provide any built-in byte swapping routines such as ntohl,
htons, etc.?
Thanks!

No, but the latest version of GNAT has a package called GNAT.Byte_Swapping.
The x86 version is written with machine code inserts.

No. It's a simple operation. You should be able to easily write a
generic that would swap the bytes in anything, if you really need to do
this a lot.

Not in a standard library.
See SAL.Network_Order.*, at http://stephe-leake.org/ada/sal.html
I used to have the SAL source available for web browsing, but I ran
out of web space; I'm working on it :).
