There was such problem with sequential API. To fix it, I think the idea was to call tcp_close, check the return value, and retry (with tcp_sent & tcp_poll) until you got tcp_close(pcb)==ERR_OK. I think that tcp_close was modified for that. About this change, take a look to the lwip_close.patch, at the end of http://savannah.nongnu.org/bugs/?20021 . I'm not sure that all changes are in the patch file, but it's a good start point. You can also check current CVS HEAD to see the "final" version. ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr <http://www.hymatom.fr/> ==================================== P Avant d'imprimer, penser à l'environnement

Objet : [lwip-users] Closing after sent
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
