Hi, After checking the 1.4.0 source code, I found it seems that doing any operation on a pcb in its tcp_err callback function is not safe. Since when lwip was invoking the error callbackup, the pcb either had been freed or will being freed shortly.
In particularly, can someone confirm what's the consequences if I call following function in a tcp_err callback: - tcp_close( the current pcb ) - tcp_new() Thanks in advance. -- Life is the only flaw in an otherwise perfect nonexistence -- Schopenhauer narke public key at http://subkeys.pgp.net:11371 ([email protected]) _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
