Raw netconn

WebNetconn API is OK, but the most flexible and effective is RAW API. And as Socket API is built on Netconn API, which in turn is built on RAW API, the latter is also the way to go, when … Webnetconn API is planned (though not scheduled), but that would still require an OS (the only benefit being one API less and slightly better performance). The idea is interesting though. Maybe we should include that in the plan... Simon--Nur bis 16.03.! DSL-Komplettanschluss inkl. WLAN-Modem für nur 17,95 ¿/mtl. + 1 Monat gratis!*

WebThe lwIP core isn't thread safe. If we have to use lwIP in a multithread environment, we should (or HAVE TO) use "upper" API layers (netconn or sockets). When using raw API you need to protect yourself and the core. Sockets generally can't be used by more than one application thread (on udp/raw netconn, doing a sendto/recv is currently possible). …
