Hi, Normally closing a connection involves freeing memory or some other tasks as well.
LwIP has a clean way to do this. Every connection has a poll callback option. If you assign a function to the connection (tcp_pool) it will be called every poll interval. If you set poll interval to two it will be called every second. You simply add an variable to the open connection to count the time. Hope that was clear.

Is SO_RCVTIMEO what I need? I use this line: int timeout = 15000; lwip_setsockopt(sock, SOL_SOCKET, SO_RCVTIMEO, &timeout, sizeof(timeout)); it always returns -1. How can I do this(closing idle connection)? thanks -- View this message in context: http://lwip.100.n7.nabble.com/idle-connection-timeout-tp23252.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************
