Re: [lwip-users] Issue with netconn_close closing connection before netconn_write's have completed

[Terry Barnaby]

Thanks for the info.

I had enabled "#define LWIP_SO_LINGER  1" in lwipopts.h which did not 
affect the issue.

But looking at the link you sent I might also have to "struct netconn* 
nc; nc->linger = 30;" or something like that to set the linger seconds 
value of a particular netconn connection. I will have a play with that.
