Follow-up Comment #5, bug #3168 (project lwip): I thought about it: another (simpler) solution would be to add an additional parameter to the receive callback to tell it the connection has closed. Or we define calling it with p = 0 means 'closed' or something. The additional parameter means one more stack save and restore for most processors, while p = 0 can mean nullpointer-dereferencing (and not everyone catches them...). I just don't like the idea of adding an extra callback that is only called for one single purpose (change of ip address). What do you think? _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?3168> _______________________________________________ Nachricht geschickt von/durch Savannah http://savannah.nongnu.org/
