Hello,
I have this implementation that uses 2 threads. One is opening a socket and the
other will trigger the close socket.
In the first thread, I call recvfrom, and it is blocking at some point in the
sys_arch_mbox_fetch(). Now, if the other thread will close(calling lwip_close)
the socket, recvfrom() will not be able to continue since it is blocking. Do
you have any idea how to handle this scenario in lwIP?
The issue is when we call lwip_close; there is an assertion "Error releasing
mutex". What we did is, we see in the netconn_recv function it is using
conn->recvmbox as its object. So, in lwip_close we call sys_mbox_post(recvmbox,
NULL) before netconn_delete(sock->conn). The operation continues as we expected
but at somepoint our application stops. Maybe this is not right thing to do?
Please advice.
Thanks.
