Hi ...
I have another question about the mboxes used in lwIP.
Can anyone tell me for what the mboxes are used. I thought there were for "inter-thread" communication. But in my case I dont have more than one thread so do I need these mailboxes. I have looked to the 6502 port in contrib tree. The standard sy_mbox_new-function return SYS_MBOX_NULL. Now my sys_mbox_new looks the same.
But if I call netconn_new(...) I came to the follwing code in netconn_new_with_proto_and_callback.
if ((conn->mbox = sys_mbox_new()) ==
SYS_MBOX_NULL) {
memp_free(MEMP_NETCONN, conn);
return
NULL;
}
Now sys_mbox_new() return SYS_MBOX_NULL and NULL is return. Now I don`t have a new connection.
Can anybody explain what the mboxes are for - then I can make my implementation of them (if nedded).
Thans and best regards
Steffen
