cfunction
(net/read stream nbytes &opt buf timeout)
Read up to n bytes from a stream, suspending the current fiber
until the bytes are available. `n` can also be the keyword `:all`
to read into the buffer until end of stream. If less than n bytes
are available (and more than 0), will push those bytes and return
early. Takes an optional timeout in seconds, after which will
return nil. Returns a buffer with up to n more bytes in it, or
raises an error if the read failed.
# in a terminal:
# $ while true; do date | nc 0.0.0.0 1234 -w 1; sleep 1; done
# in a janet repl:
(net/server "0.0.0.0" 1234
(fn [conn]
(prin (net/read conn 4096))
(net/close conn)))
# note: output doesn't actually start until you (quit) your repl's fiber:
