SEND does or doesn't send all data?

Question

Hi, I’m new to these devices, but have a W5500 working nicely with a PSoC microcontroller using my own library (which is very much optimised for RAM efficiency, so I can’t really use the standard library.) One question I have though is that the data sheet for the W5500 implies that the SEND command will send all the of the data, whereas the wiki page… https://wizwiki.net/wiki/doku.php/products:w5500:application:tcp_function … calls out the fact that not all the data might be sent and I should see how much has gone and re-send if necessary. BUT … when I look at the provided library I see that it doesn’t do that, it just waits for SEND_OK and then continues. (There is some code that seems to do this, but only for the 5200.) So … does the SEND command for the W5500 send all of the data or not? Thanks. Lee.
