If it's a question of efficiency, to be really really sure, maybe read the UDP packets off the wire/port with tcpdump, which despite its name is quite happy to capture and show UDP too.
tcpdump -i lo udp port 9000 -vv -X
You'll see any byte order munging or padding due to some NIC/network stack setups. On my Debian systems it is indeed plain bytes.

hi,
i want to minimize the data stream send through an UDP connection
by sending 'coded' bytes; the receiver(s) will decode them.
i'm unsure about the meaning of 'raw data' in the helpfile of [udpsend].
does [1 2 3( represent bytes with the octal vaue 001 002 003,
or the integers 1 2 3 which will be 'translated' into the octal bytes 061 062 063 ?
it's a bit ambigious for me, especially comparing the helpfiles of [iemnet/udpsend] and [mrpeach/udpsend].
with the iemnet version one cannot send files directly, it's necessary to use [binfile].
does it mean that the mrpeach version recognizes that a file is used for input;
wow that [binfile] is embedded in its [udpsend]?
