LWIP - threadsafe

[Reiner1210]

Hello,

If I have a server application I get a socket via accept.
Is it now possible to use 2 thread which use this socket ?
One thread will read from the socket and the other one will write to this socket.

Thanks for your help

Hi Reinier,

Yes, this is supported and should work as expected.

It's even possible to close the socket while another task is blocking on read/write: https://docs.espressif.com/projects/esp ... fe-sockets

Thanks for the answer.
What should be used:
The lwip function or the "normal" function ?
e.g lwip_accept or only accept ?

You can use either but we recommend calling the standard functions - ie accept(). But they compile to the same thing.
