SV: [lwip-users] Closing after sent

[Jan Wester]

It works well for me, but what confusing me is on ethternet trace, the close from lwip FIN/ACK comes before rest of the data,

the receive side has not start close, half duplex mode ?

Ämne: RE : [lwip-users] Closing after sent

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.

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 ?
