Hello, I am using code similar to std::ostream, writing to open TCP connection.
Without buffering (calling netconn_write for each small data chunk), performance was an issue, so i implemented simple buffer (over 1kB) to write data to buffer first, and when buffer is full call netconn_write. I was considering if i can avoid this extra copy, by pre-allocating sth like pbuf - filling it and then passing to lwip stack, but it seems tcp connections only support copy based approach. Am i right or have I missed something? Regards, Krzysztof Wesołowski,
