Unfortunately, the existing 'udp' function cannot do that. It can handle
only Lisp data.
You could make your own custom function, e.g. with inline-C using 'gcc'
(load "@lib/gcc.l")
(gcc "net" NIL 'rawUdp)
any rawUdp(any ex) {
...
byte buf[UDPMAX];
...
fill 'buf' with bytes
sd = socket(AF_INET, SOCK_DGRAM, 0)
sendto(sd, buf, ...)
close(sd);
}
/**/
but this is rather tedious, manipulating the buffer and byte data.
I don't know any really easy way at the moment. How about writing raw
bytes to a pipe or temp file, and using an external tool like 'nc' to
actually transfer the data?
Cheers,
- Alex
