[lwip-users] Closing after sent

[Jan Wester]

Hi

Using lwip 1.1.2 with raw interface

I'm sending a file with lot of data and using callback routine tcp_sent, how can I verify if everything has been sent

before I close. I have try to close on end of my file, but it is to fast, It is still data in the buffers.

Shall I check the len parameter on the callback for tcp_sent or what ?  

 

Med vänlig hälsning/Best Regards
Jan Wester
