Except that I'm writing a network interface that should be specified so
that externally written programs can read my data.
In fact, your post reminded me of a chapter of "The Practice of
Programming" by Kernighan and Pike. They advise to read/write integers
byte by byte using 8 bit masking and shifting.
So I'll follow that approach, which is close to yours and is independent
of machine endianness.
Thank you for the tip, ;-)
Yours,
d.
