This brings up a second question. How should I do byte order
conversion for 8 byte ints? I can't use hton ntoh routines as they
max out at 32 bits. Is there a better way? Also, are floating point
numbers guaranteed uniform?
If any one knows a a clean code example of binary binding of
parameters and binary extraction of results for all major types in C
against lippq that would be a very useful thing to have in the
standard docs.
