[lwip-users] netconn_write, "Flush" functionality

[Walter Saegesser]

Quite a long time ago a read somewhere – don’t ask me where, it was not on this mailing list – that a statement like “xNewConn->pcb.tcp->flags |= TF_NODELAY;” would force the netconn API to write data out immediately.

What is the behavior of netconn_write if this flag is not set, i.e. what is the criterion to actually write the data?

Is there in the meantime a more appropriate solution to flush the buffer at the end of a sequence of netconn_writes?

 

Thanks a lot.

Walter
