[lwip-devel] [task #6735] Provide new pbuf type: PBUF_RAM_NOCOPY

[Jonathan Larmour]

Follow-up Comment #3, task #6735 (project lwip):

Re comment #1: yep there's a lot of good things that become possible once we
have a way to know what we need to do with a pbuf.

Re comment #2: Since TCP is stream-based, I'm not sure why people would want
to use pbufs over the existing char * and length. Protocols that send dynamic
data can just send the char * and length directly, rather than having to wrap
a pbuf around it. And tcp_write() already takes a 'copy' flag after all.
Unless I'm misunderstanding what you're getting at?
