I would look at SCTP socket API it supports multistreaming.

SCTP is very telecom-shaped; in particular, IIRC, the number of streams is fixed at the start of the connection, so (this sucks but also) GP’s problem does not appear.

  • That problem doesn't appear, but also trying to pass off a stream as a readable/writable thing to a polymorphic interface ("everything is file") wouldn't work.

    ...however sctp_peeloff (see other thread) fixes the issue. Hurray!

API RFC is https://datatracker.ietf.org/doc/html/draft-lxin-quic-socket...

  • Ah fuck, it still has a stream_id notion

    How are socket APIs always such garbage....

    • At least the SCTP API has sctp_peeloff, which gives you a new single-stream socket descriptor for the connection. Maybe QUIC will get something like that, eventually. Kind of a glaring omission, though, unless I'm misunderstanding.

I checked that out and....yuck!

- Send specifies which stream by ordinal number? (Can't have different parts of a concurrent app independently open new streams)

- Receive doesn't specify which stream at all?!
